Depending on the zoning of your property, the configuration of your lot and the construction of the garage, you may not be able to get a CO from your city for the extra unit.Your best bet may be to make use of the space yourself, provided that your tenants still have proper parking.

Best bet if he/she wants to stay they must sign the lease or leave the property.

How are companies like invatation homes, american homes 4 rent, silver bay, progress residental, way point homes, aquiring so many propertys when theres a shortage of houses?

This area of Massachusetts is also very progressive in ideology, particularly environmentally.

And I'll bet the market is very workable... you're going to do great there. 

Thanks for keeping up posted with your progress.

Your best bet would be to find an owner that is open to seller carry.

I'm betting about 80k or so mortgage aside.

Seller financing is an equity based loan, look to the UCC as to default of installment contracts, they become void, points or loan fees are not charged on equity financing.......I said not charged when I should say, should not be charged as I'd bet sellers are not in compliance, they can just lose their note and suffer any consequence that goes with unlawful lending.

My bet is not necessarily that the listing agent has another offer for a higher price, but that he or she has another offer from his or her own client, thus a chance to get double the commission.
