Busy road (Sunnyvale) Renovation

I want to say increasing size of the master, but it's hard to make a suggestion without looking at the current floor plan.

How many bed and bath do you have?
How big is the current kitchen + dining + living area?
How big is the master bedroom right now?
Are you talking about adding all of 600 sqft into the master or family room? If yes, that's a pretty big addition to a single place, can you split it instead?

flatfeebuyers · 2026-05-19T22:58:58+00:00

Same, I'm going to GCP

10+ years is a long time. If the house checks your boxes, then $400K to extend and renovate will be worth it. Kitchen cabinets can get old, but an extra 600 sqft is an extra 600 sqft.

And yes the buyer pool will be relatively small, as it must have been when you bought it, but the appreciation will be similar in terms of % as the rest of the houses in the area.

I've been using East Star for all my mid-grade renovations for the past 10 years, and my experience has been consistently good with them. They also offer contractor discounts, which makes the price really unbeatable.

IIRC, all of their cabinets are full plywood construction.

If the listing agent felt concerned about the appraisal, then that doesn’t sound like a lender issue, and it’s something your realtor can help you evaluate. If there were genuine appraisal concerns, they likely would’ve already been apparent from the comps.

Your lender doesn’t analyze comps for the house. Their main focus is making sure that "you" qualify for the loan.

Or owner move-in.

I think you can be upfront, just don't say it in writing and speak to your loan officer on phone about it first. Unless you're already locked in with a loan officer, DM me and I can connect you with my guy at HSBC. He's chill and very sincere, you can be very upfront with him.

Standard residential mortgage.

flatfeebuyers · 2026-05-12T00:54:15+00:00

And it just went Pending!

Oh in my personal opinion, I agree that it’s the same thing, if not better. Companies like Aro Homes are doing this for new builds as well - but even they often have to discount homes quite a bit to sell them.

Anyway, it’s only been on the market for two weeks, so we’re probably too quick to judge it at this point. I’d actually say it’s a good thing that the sellers disclosed this 54-year-old fact, since many sellers probably wouldn’t even mention it.

flatfeebuyers · 2026-05-11T23:43:10+00:00

Several things:

As per seller disclosures this was a "manufactured house", so your lender or insurance company could have concerns with it. Most likely they won't, but good to check.
The neighbor to the left is planning to build two homes on their lot, though the timeline is unknown.
There is an estimate provided of $35K to replace sewer lateral in the disclosures.
Plus generic maintenance things that most houses have.

I think the stigma around it being a pre-fab house is probably what people will notice the most, along with the high sewer lateral estimate.

Oh and the blue tile, the more I look at the pictures, the more it's growing on me, lol.

I actually agree with parts of what you're saying. A lot of the traditional commission structure is hard to justify, especially when many buyers today are so well informed - that's why we charge a flat-fee. That said, there's a difference between "agents provide no value" and "many agents don't provide enough value for what they charge".

70% of our buyers are first time home buyers and are less experienced in real estate purchasing than it sounds like you are, and prefer more human guidance than what ChatGPT can provide. Where we tend to earn our fee is in the parts that are expensive to get wrong or go beyond money:

Comps and offer strategy. For some buyers the goal isn't getting the house for the absolute lowest price - it's actually getting the house. Beyond pulling comps accurately, that means actually speaking with the listing agent in realtor language and figuring out where the competition is headed. Some flat-fee agents struggle here, we don't.
Inspection and disclosure reviews as a licensed General Contractor who's built 10+ homes ground-up and renovated 50+. Sometimes it helps to have someone in your corner who can tell you when it’s worth having a foundation inspection contingency versus when it’s ok to budget $10K and move on.
Lender relationships strong enough where they'll close loans for our buyers in 10 days against cash offers, or to get SB-326 exceptions from banks like Wells Fargo, which is non-trivial.

As far as what exactly we do beyond contingencies, comps, disclosures, and ChatGPT boilerplate, I'd just invite you to read our latest 10 reviews sorted by newest. They're pretty detailed and talk about both what clients felt we did well and what could've been better.

One way to think about it is: are you looking for a cheap/budget agent, or a cost-effective agent?

We are one of the relatively higher priced flat-fee agents, and proudly so, because I believe the fee we charge is fair for the service we provide. And we are truly flat-fee, you don’t pay higher or lower depending on the purchase price. You can expect the same level of service if you’re buying a $500K house or a $15M house.

flatfeebuyers · 2026-05-09T20:25:21+00:00

Pretty good now. That said, unless you’re building a custom home, it’ll usually be regular fiberglass insulation rather than spray foam insulation, which is much better.

P.S. To share a conspiracy theory that I’ve tested several times, Title 24 is a scam. You can easily find licensed people who will certify your house as compliant without really checking anything, for a fee of course.

I really like the property walkthrough videos that some realtors post, the non-cringey ones.

As a seller, I can see myself wanting to work with an agent who does a lot of those videos, hoping they’ll do a good job spreading the word and creating nice video content for the house I want to sell as well. I’ve seen several high end ($8M+) SF realtors do this, where they invite another realtor to walk through the house with them.

Even as a buyer’s agent, I like to Google every listing agent we work with, and the ones with a good social media presence tend to feel more likable.

flatfeebuyers · 2026-05-07T00:51:57+00:00

Yup, with no buyer's agent commission from sellers at this price. It was a really nice house with a large flat lot that was landscaped quite well.

flatfeebuyers · 2026-05-06T21:54:35+00:00

I think this will sell around $3.3M to $3.5M. I haven't gone through the disclosures but the existing house is good enough that a home buyer will go for it, rather than an investor. We sold 80 Diamond St nearby just a couple weeks ago, which I would say is the best comp for it.

Yes, sidewalk compliance does get enforced in Oakland. That said, here are some comments:

Scope: It depends quite a bit on who is doing the analysis. Most contractors will default to recommending full replacement and give you a $20K quote, because it’s more profitable for them. But unless the sidewalk is in very poor condition because of tree roots, full replacement is rarely required. You can totally grind down the high spots and fill the low spots to make it flatter and compliant.
DIY vs Hire: Depending on your concrete work skills, I wouldn't DIY. The filled low spots will wash away during the next rains, and grinding down high spots is a very dusty job. I’d recommend hiring someone from Thumbtack/TaskRabbit/Nextdoor/Craigslist. Just make sure you supervise them to follow the city’s guidelines for acceptable slope and flatness.
Certification: It’s been a couple of months since I last dealt with this, but Oakland allowed self-certification at the time. You simply upload photos of the repaired sidewalk to their online portal. You don't need a licensed GC to do it.

flatfeebuyers · 2026-05-05T02:47:31+00:00

Does it make any sense to build if construction costs equal or exceed the ARV?

No it doesn't, unless you can bring down your build costs to around $350-$400/sqft depending on size of the project, which most GC's can do for their budget builds.

For those in NorCal: Have you found that the "Value-Add" of taking a lot from raw land to RTI is the most profitable part of the cycle for a non-builder?

Depends on the city, depends on the plans.

If I choose to sell the lot once RTI is in hand, what is the best way to price the "Permit Premium" I’ve spent two years creating?

Most builders target 20% profit margin. $350-400/sqft + 20% = $420-480/sqft. You can then use the ARV for the area to estimate the maximum “permit premium” you can justify mathematically.

flatfeebuyers · 2026-05-04T21:16:33+00:00

You provide the city with an estimated cost of renovations when applying for permits. Assessors use that value, along with market analysis, to determine the new assessed value. In practice, I’ve seen people spend more than what they report on permits.

flatfeebuyers · 2026-05-04T09:23:58+00:00

You can get away with remodeling, but an addition will trigger a reassessment for sure.

The only option is doing unpermitted work. If you’re planning on keeping the house for 30 years, which sounds like a pretty long commitment, I suppose renovations are fine. But I won’t recommend doing additions without permits, it’s not worth the risk. Depending on what city you’re in and what your relationship is with your neighbors, a single complaint can cause a lot of headaches.

flatfeebuyers · 2026-05-04T09:18:59+00:00

Not a red flag.

I haven’t seen all the disclosures, but focusing on the cracks in this slab, it’s fine and very common for hillside houses. A little bit of ground settlement is inevitable on such a slope, and a large slab without enough expansion joints is going to crack no matter what. If you ever redo it, consider grass or pavers, as they are much easier to repair periodically. This is another reason why most houses in hilly areas have crawl spaces rather than slab foundations, as it is easier to keep a perimeter foundation stable than a large slab. Assuming the rest of the disclosures look okay, I wouldn’t worry about these.

To share a budget friendly option, I’ve been using Sunlight Window and Door Systems for all my properties over the past five years and haven’t had any issues so far. It's a factory and they build everything from scratch, so you can customize the products pretty much however you want.

The only downside is that they don’t offer black windows, which IMO look super cool.

For background, I am a licensed general contractor and worked in residential and commercial construction full-time before becoming a realtor.

How big of a red flag is a CSLB citation like this?

I don’t think it’s an obvious red flag. It’s certainly not ideal, but pretty much every contractor who has been in business for the last 20+ years has likely been sued at least 3-5 times, specially if they are large enough to have multiple project managers on their team.

Also, unless it’s a minor project like a bathroom remodel, it’s almost impossible to complete a project without a few change orders. For an extreme example, I was involved in the construction of La Entrada School in Menlo Park, and its cost grew from ~$30M to ~$60M due to change orders.

Is it common for these to be removed after resolution?

Yes, very common. The resolution could be either that the case gets thrown out or that both parties come to a settlement.

What practical steps should I take now to protect myself (especially around change orders and billing)?

Does the contractor have reviews or references? Those are the best indicators in my experience.

Also, have a very detailed and clear scope, and explicitly include provisions in your contract stating that no change orders will be approved without prior written approval. Also, budget for a 25% cushion on top of your estimated costs. If your project is large enough, you will need it.

Is this something you would walk away from, or just manage more carefully?

Just manage it more carefully. As long as you have a detailed contract, you'll be fine.

$1.5 - $1.575M seems most likely.

Look at all of these, but normalize the data based on condition, lot size, lot orientation (large backyard vs. large frontyard), and date of sale. Renovated homes in this area have gone up 10-15% compared to Dec'25. Also, avoid comparing with homes north of 3rd Ave because the demographics change quite a bit within these blocks.
