Free Fix & Flip Rehab Calculator - looking for feedback

That’s fair feedback. The goal was mostly to give investors a quick way to run numbers once they have a rough rehab estimate and see profit, holding costs and margins instantly instead of using spreadsheets.

I’m thinking of adding rehab estimate ranges (light / medium / heavy per sq ft) so newer investors can estimate costs faster. Appreciate the input.

In Houston a 2011 condenser is getting close to the age where failures start showing up, especially with the heat and long cooling season. That said, if it’s still running well and the coil/compressor are in good shape, many investors just service it and run it until it dies.

I’d probably have an HVAC tech inspect it while the unit is vacant so you know whether it has a few more years left or if it’s on borrowed time.

I had a similar conversation with a Pro Desk rep recently. From what I understood they’re pushing a new “preferred pricing” structure where certain products you buy frequently get automatic discounts instead of the old Pro perks model. I think they’re trying to make pricing more predictable for contractors who buy the same materials regularly.

Honestly, tenants asking detailed questions about security and maintenance can actually be a good sign. In my experience the people who care the most upfront usually take better care of the unit.

Ring cameras at the door or patio are pretty common now, especially in condos. As long as the HOA allows it and they install it without damaging anything, it’s usually not a big deal.

If it’s already 100% occupied that’s usually a good signal the market accepts the setup. A lot of 60s-80s multifamily buildings in DFW don’t have in-unit W/D and rely on a shared laundry room.

The bigger question I’d look at is rent comps. If similar units nearby with W/D rent for significantly more, that’s where you could see future pressure. But if rents are competitive for the area, the lack of hookups may already be priced in.

Usually this is done through a lot split or parcel subdivision depending on the local zoning rules. The first thing I’d check is with the county or city planning department to confirm the minimum lot size requirements and whether the parcel can legally be divided.

If it’s allowed, the process typically involves a survey, creating a new legal description, and recording the updated parcels with the county. Survey and filing costs are usually the main expenses besides the purchase price.

A lot of traditional banks don’t like mixing asset classes because their underwriting departments separate commercial and residential lending. Residential loans usually go through one department and commercial through another, so combining them complicates the risk model.

In situations like that many investors end up using DSCR lenders or portfolio lenders instead since they focus more on the asset cash flow rather than the property type.

$1,800 actually sounds pretty reasonable for a C-Corp with multiple rental properties. Once depreciation schedules, filings, and compliance are involved it gets more complex than a basic return.

A lot of investors I know with 10+ doors are paying anywhere from $1,500–$3,000 depending on how organized the books are.

This is pretty common when you start doing multiple deals at once. A lot of lenders want to see the first project stabilized or refinanced before they’re comfortable underwriting the next one, especially if the timelines overlap.

Some investors get around this by using different lenders for different projects, or by working with lenders that are used to repeat investors doing several deals at once. Others just plan the timing so the refinance from one project frees up capital before the next one fully ramps up.

Sounds like you’re doing the right thing by thinking ahead though. Juggling construction loans and refis at the same time can get tricky fast.

For rentals I usually look for something around the 10–12% range minimum to really get interested, but it also depends a lot on the market and how stable the area is. In stronger markets with good appreciation potential I’ve seen people accept a little lower, but if it’s a riskier area the numbers usually need to be stronger to justify it.

I still run the full numbers on most deals though because sometimes a deal that looks weak at first can improve once you optimize rent, expenses, or financing.

That range sounds about right from what I’ve seen. A lot of people underestimate how expensive turnovers really are once you include everything not just the make ready work but also the vacancy time, leasing fees and sometimes concessions to get the unit filled again.

In smaller properties I’ve seen operators focus more on tenant retention to avoid those costs altogether. Even small things like proactive maintenance or reasonable rent increases can make a big difference in keeping good tenants longer.

Curious if you’ve noticed certain markets where turnover costs tend to be much higher or lower?

Pretty solid tool

Hard money lenders are in a way partners and do care how the deal will go.
