For anything less than that with a traditional bank or credit union, you'd likely be looking at a portfolio product (the bank/CU will hold your loan and not sell it on the secondary market). 

Take for example, while representing buyers in single family transactions, during the negotiation, I ALWAYS ask the sellers to credit the buyer(s) up to 3% of the asking price toward the buyers costs.

You can do all the prequalifying from anywhere via credit check, call references, verify income etc.Make sure you have a handy person, ac person, plumber, etc etc that you can call when you need some work done. 

I’ve been documenting multiple comps close to my house tracking rents and it seems like my house would rent around $2,000/month.

That's a real bait and switch scummy thing to do, but I guess I shouldn't be surprised these days. keep in mind this is not usually bait and switch it could be and they are not being scummy.they simply are at the whims of thier senior credit facilities wants and needs..

It's going to be an obvious patch job when they do inspections and they may ask for credits or replacement so you are more likely to get more by doing more.I don't know any roofers in Canton, but any time I see patch and roof and sell, I don't think it's necessarily wise.

-Should I ask for credits to repair? 

Before you get too far, I would go talk to every local bank and credit union in the area you want to do this. 

You will also have a credit on statement for pro-rated taxes due to buyer.  

Thanks Judy, hopefully they will get back on track with their investors.
