Quote from @Andrew C.: I have an STR in Niagara Falls and it does pretty well based on the purchase price. 

.- I've read about A, B, C, and D class properties. 

Most utilized is Reg D Sec 506 b or c.  

I don't know if I will do the a/c and heat but might do dishwasher and w/d soon.My dad bought the building in the 70's when I was a kid.

@Martti Eckert here's the big issue that no one really talks about that you hopefully find helpful (this is copy & pasted):-----------------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Buy it personally, and rent it full time to my C-corp?

U can check out  ivyridgeestatescanby dot com for my 90 home project in Oregon that I did with my oregon bank and then my website for pictures of homes we built in Charleston SC which is the only market I tagged HML ( lima one) and only one time the rest were done with Ameris bank or Service first bank that is local in the market. its all about the three C's  Character Collateral and capacity..

Class A and B neighborhoods are above median price and C and D are below.

You'll likely need to be in a C/C+ neighborhood to find the 1% rule, but you can still break even or sometimes get some slight cash flow in the B neighborhoods of Columbus.
