My easiest and safest bet would be to just build the outside storage lot.

FB Marketplace is probably your best bet - You can try craigslist too but at least with FB you can do a quick scan of someone's profile before talking to them. 

When i signed up, I couldn't find any reviews on BP and I hope this helps people make the right choice.1. they make it sound like they do a lot more work than they actually do.

While doing an Airbnb seems like a good idea it does not resolve the issue of the divorce and splitting the propertyI still think your best bet is to drop the price and sell it and start your life over.

15 acres for a lot sounds huge to me and I'll bet you could be missing out on some extra $ by not getting more lots.

I second what Jonathan Greene is saying here—turnkey is probably best bet given your constraints.

I’m also not a fan of buying a property that loses money every month, while hoping for appreciation and betting that interest rates will fall.

Using the 1031 Exchange is THE way to defer capital gains taxes and use your equity to purchase additional properties.re: the Pittsburgh market...it can be a good choice.

It's hard to say for sure without knowing your market numbers, but I would bet you if you looked at a 10 year projection, you will probably have a better ROI with the equity in 2 houses as opposed to the equity and cash flow with one. 

This way, Tenant A gets a little financial "help" beyond their actual expenses and for Tenant B, it's a total choice to take advantage of a W/D or not.
