Lol, throw in 12B, or use keller mortgage, cause they pay the closing costs and give you a $1000 credit. 

There is massive opportunity cost throwing more money after bad investments

Find rent of rooms similar to yours, Look for extras, and as @Stephen Bianes mentioned throw in all utilities and price them slightly lower or higher depending on your room's attractive amenities. 

Usually they will also jackhammer all of the concrete decking as well as the first 2 or 3 feet of the pool wall and throw it into what was the pool bottom. 

But in my experience you will ultimately throw good money after bad with these broke idiots .most of these folks have trash credit and could care less .

Then if easements or something throws you a curveball, you have much stronger grounds to create an objection they can't cure and get out of the contract.

You can argue whatever you want about the way someone is implementing data and automation and i would agree but saying is a waste of time is throwing the baby with the bathwater.

If it was sold As-Is or from a wholesaler you need to check how that contract is written because sometimes they throw in tricky wording. 

I have an apt building in Class C I literally have a tenant who doesn’t throw out trash and the PM has to babysit him (he pays on the first of every month always)- Vacancy isn’t necessarily more and turnovers aren’t always higherMy strategy is I take a property in a Class C area and make it a Class A/B property.

However, when I think about it more, if you're not paying very much in interest on the debt compared to how much you could be gaining in an investment property it would be better to throw all the money at an investment property.With interest rates so low on primary residence loans, I think it makes sense to buy a primary residence and keep chipping away at your debt.
