Is it DSCR or something else?

Do you want to scale more and maybe sell this property and 1031 into something else that may cash flow more, or hold onto it because the cash flow is pretty steady it sounds like. 

And the cracks mostly follow the drywall seams from what I can see, which is typical....And as @Patricia Steiner said, it doesn't look like a pro installation....You could ask the Contr to use a flexible compound if this happens again, or maybe even now...https://www.dap.com/products-projects/product-categories/pat...Like everyone else said, I'd have it repaired - by a licensed Drywall Contr. - and then just check in on it.

And if you recognize it is a good time to buy won’t everyone else see that it is a good time to buy too and then jump into the market and drive prices up?

Simply fire them and hire someone else.

I won't pay more than what it's worth to me, regardless of what someone else paid for it.

Once the year passes you can move out, rent and repeat or try something else. 

When we order the appraisal everything will come up so it will need to be listed correctly or else the 1007 will come in low.3.
