By continuing to support a system which has stolen millions of homes from American people, for your own profit,  you are a part of the problem.  

I can only speak to myself personally but I've continued to invest, knowing properties may not cash flow much but I've invested in value-add so focusing on appreciation.

If you believe it will continue to appreciate (like most of San Antonio), I would hold on to it even if there's a bit of negative cashflow for the first year or two. 

When you do that, you can get better pricing and leaves less room for error.The best advice is to push forward as quick as possible, fail forward, and always continue to introspect on what you would do differently and then ACTUALLY go back and implement that change (easier to say than do).

At this point, instead of continuing to pay the interest loan payments on properties that we will never be able to financially finish since the rehab loans will not cover the actual cost of the rehab, I wanted to know the ramifications of returning the properties to the loan servicer, deed in lieu.

I also hope airbnb does not continue to get less host friendly.  

That seems like a more realistic result than just “talking to the bank” and having them agree to let the arrangement continue.

Personally, if your market tends toward the former condition (better/normal appreciation) I think it's a fairly safe deal looking at the long term, assuming infrastructure around you continues to support the idea of renting it.

Places like Texas where you’re at will likely continue to face significant insurance increases given more weather related events which makes it challenging To pencil, but if you have good population growth, things should even out.
