I met this mid age woman at the property and she seems nice at that time. 

The Internet has made it easier for you to advertise your properties, so being located on Main Street is not as vital as years ago.C properties have higher cap rates than B and As because of their age, and the fact that they contain less appreciation, unless it is forced.  

Our goal was to reach financial freedom in 15 years, by age 45, but weren't sure if it would be possible. 

Just wondering about age of home and whether you got sewer inspection, as that’s not usually covered under the standard home inspection.

Given the age of the house, that's a nice-looking solution.

If you are unable to borrow from your plan, or if you need more than you can borrow, then you may be able to take a taxable distribution if you are age 59 1/2 or older, or no longer work for the employer that sponsors the plan.

It's good that you have a 15+ year picture, everyone wants to get rich in a year it seems.I agree with @Tom Parris comments about property age. 

Anti-discrimination (fair housing) laws in MA are no joke. 

Based on past operations, age and condition of building, was it rehabbed or does it have deferred maintenance, I typically use $50 per unit per month as a starting point for R&M.

NOPE 500k.. they super size it.. there is no conservative nature in 90% of these folks and that's why you have these folks in financial straights many times .. needing credit repair .. failed marriages etc etc.the inability to control their personal financing.. they should all be listening to Ramsey.Investors now are a different class completely.. you cant in todays day and age be an investor with only a few grand to buy a home like a homeowner can.
