For existing lien, you do not have to wait for any period.With small banks or mortgage brokers; they are flexible and can have exceptions based on your assets, credit score and rental income.

It is possible to obtain an owners policy on a tax deed without a quiet title action with an added exception for marketability. 

So I'm looking at a house that looks pretty good except for some seemingly minor foundation settling.  

Most states, except those listed as community property states, use the COMMON LAW system of property ownership.

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.
