At this point I will have pick up about $450K in appreciation after sales costs, but that is before taxes and I am in a high bracket. 

I would highly recommend connecting with @Josh Brook

Given the potential for high returns, customizable involvement levels, and significant tax benefits, I believe this is a great investment opportunity, particularly in markets experiencing rapid growth.I've been keeping an eye on developments in Georgia, where builders are struggling to meet the surging demand driven by population increases in certain areas.

Most of the houses that were sitting on grade were  completely or almost completely under water.

Acquiring an income earning property with high potential for appreciation for less than $20k out of pocket?  

I would highly advised from borrowing from your uncles until you are much farther along in the process. 

I would say there should be a few options at that loan amount - the most common minimum for DSCR lenders right now probably more like $100k or $125k - I would say only a small portion have as high a min. as $150,000

Unless you are an experienced builder, securing a bank loan can be difficult, and hard money loans often have high interest rates, which can become costly if your project faces delays.

We use a lot of caulk on damaged wood to help fill in gaps, etc - especially up high on the sides of houses.  

At these rates, it seems like it would be better (for now) to wait on the sidelines and get a high-dividend REIT.So my questions are:1.
