The water is billed quarterly, and I am afraid that if there is a leak somewhere I won't know until I receive an enormous water bill.

This google docs sheet provides a list of pass/fail rates for different courses, but I figured someone here might have input if any of them are better suited for investors.https://docs.google.com/document/d/16a8x8_N4aO6HVv...Thanks!

I assume that you received and recorded these docs from the seller of the NPN when you bought it.

@Michael Zack Here are the applicable lead paint laws in MA: http://www.mass.gov/eohhs/docs/dph/environmental/l...Bottom line: You cannot refuse to rent to a family with a child under 6 years of age - even though your property has not been de-leaded.  

Just make sure everything works and no big leaks

Then I take out a commercial loan for ((market_value+1)-$300k)=$50-75k-ish,  buy it for market_value but only pay her the difference, somewhere in the closing docs have my mom "forgive" or "re-assign" the $300k loan, and between her and I we would have a separate agreement and I'm not sure of the terms.

Then they take 48-72 hrs to provide funds once all the docs are in.HM Lenders still go through an approval process like any other lender.

Safety, no open flames or risk of gas leaks.

I had a roofer go up and take pics that showed roof needed replacing with quote to replace,  basement had water issues with quote, a leak from shower which showed in laundry room, with quote.  

We have closing attorneys in NC so once I have a signed contract I send the paperwork to the attorney and he will do a title search and prepare the closing docs.
