Another one was seller-financed for a few years before refinancing into a conventional loan around 2018, again no issues until this year.

He was more expensive because now I gotta pay someone else to fix it.But here's the other side of the license issue.

Of course when doing the 1031 exchange your basis will carry forward into your replacement property.Where you have a potential issue is establishing your intent to hold those properties but immediately selling one or more them as soon as you have them ready. 

Had an issue with trying to self-permit a build a few years back that was an HPR but had an "A" and "B" designation.

Good news is our land is where all of the next-door houses are (free houses, I think legal issues). 

Even in towns where they desperately need affordable house if, they can’t get over the stigma of MHPs.The other issue you’ll run into is highest and best use.

Purchasing a STR in a somewhat sketch area is a terrible idea and as others have mentioned, is going to open you up to potential issues. 

One of the issues I have noticed is that some people think of a flip house as being the cheapest possible rehab. 

So, the actual seller is probably not the issue here.

For legal, we can provide you a list of attorneys out there who do this and my recommendation is to interview them to see which one you feel works best for you.
