Any special or unusual RE rules that I should be aware of at Ohio?

We are just uncertain of the restrictions when it comes to a refi to get our $ back out to reinvest. 

I have an unusual question that hasn't been asked on here a lot.

It's not unusual for Section 8 payments to be delayed, especially when dealing with HABD (Birmingham).

That would be the highest cap rate in DC, making this property unusually cheap...and theres a reason for that even if its not easily evident.

I have what I think may be an unusual inheritance situation.

That paper will be of uncertain value, and since you don't really know what you're doing, chances are good that the note will end up worth less than you expect, as your end note buyer will be looking at borrower credit, payment history seasoning, initial down payment, current LTV, rate, term, balloon feature (and whether refinance at balloon date appears feasible), etc.

When purchasing, everyone wants cash flow from day 1, great if it happens but that's unusual. 

If you're willing to spend money to be REALLY good at valuating real estate really quickly, I have an unusual suggestion: Interview 3-5 appraisers, pick the one you feel to be the most intelligent, and hire him to appraise some residential property, with the understanding that you want him to sit down with you and explain the appraisal in detail once it is complete. 

In all but the most unusual cases, a simple visual check will tell you whether the vent is properly terminated/capped, so I would expect my PM to be on top of that.As far as cleaning the vents, I agree, they should be cleaned every few years.
