I made every mistake, I probably could have made, except actually take payment of funds and give them the keys.

This number may seem exceptionally good and it is.

Except there are furnaces for every unit, and water heaters for every unit etc... 

I don't know of an active one in the Springfield area, except for the CTREIA in the Hartford area.  

The exception is if it is a HUGE, six figure renovation, then add 50% to it on your first few. 

Your option over a period of time can be cause for a lender to exercise the due on sale, as to the end byer paying it off at the end, really no issue, the loan is to be paid off at settlement, the lender won't be involved except in giving a payoff and settlement instructions to accomplish the payoff.

If both tenants renew, I won't have to do anything, except the porch.

It will have an exception for the loan that's being left in place.  

This is vital.  

There are very few upgrades in the house with the exception of a few things like wood floors.
