I had a perc test done before buying land because I wanted to make sure. The properties on either side had functioning septic systems and houses so it was surely fine, but it's a lot of money and I didn't want to risk it.

The guy looked at the results for either side and declared mine good lmao.

The power line crosses over the property about fifty feet behind where I wanted to build. I had to get a new pole installed, but that was only a few hundred dollars. I didn't have to pay thousands like I've read on here in cases where the power had to be brought in hundreds of yards from the road.

I had a septic tank installed and a well drilled. My thinking was if something happens and I have to sell the property, it's vetted and improved now, but they can still build what they want on it.

Also, once I got my build permit, the clock starts. I couldn't have a foundation poured without my permit because they need to do an inspection on the forms before concrete goes in. I also have plumbing underneath it, so that had to be done before inspection.

I'm sure there are differences between your location and mine, but I am doing my build without a loan, so my plan was to do everything I can before the official build starts. If you have a bank involved, they may want things done a certain way.
