Even if you have a preliminary approval from zoning, you still need to determine that it works with your specific site constraints. 

I'd wager then I invest in 90% blue cities in 100% of red states for my true REI.

There were some questions from the underwriter about me having enough assets but they were addressed (or so I thought) as I got the preliminary closing disclosure.

It happens that the facts in Wake county didn't support my preliminary expectations.

Throw in the fact its a county seat, has access to not only rail, but regional air, three US highways, two state routes and a state park, and I would wager there should be many more than 10,000 people there.

My preliminary research indicates that this might be possible (without committing fraud!)

I wouldn't likely/necessarily be mailing a lot of letters for example.But mainly, I would pay for a service that offered me the closest thing to an instant/on demand "preliminary title report" , that is something that greatly "simplified" initial research, preliminary only of course- based on apn.

I have used it for a preliminary check.

Preliminary rehab estimate by PM is 35k.Will be glad if you have contractors you like and recommend.

We wagered it would cost less if we just spent time sourcing the right people.
