., our builder estimates this project would have been ~$37K - ~$55K less 2H 2020) Any other critiques / advise?

This is why i dont advise buying one house as an OOS investor. 

It is hard to advise someone with a bad track record that investing is the best way to get out of debt.

If at any point you hit a road block and feel it is to much to handle I would advise hiring a public claims adjuster to get your claim maximized and completed faster.

Also I wish to read if there are any books I can read related to selling a property.Thanks As a licensed realtor, I will advise you that the seller always has the final say when it comes to pricing terms and accepting offers.

Any suggestions or tips please advise. 

Great advise. 

@Jessica HuynhI think @Zack Karp or @Michael Facchini would be better able to advise on this but I'm guessing that you're unable to get pre approved on your own as the sole borrower, correct?

Our construction general manager on our team is advising us against doing this right now, unless you are ready for longer than normal construction times and higher costs.My opinion is to look for value add if you can.

If so, any advise on firms or companies to work with that you have experience with.
