There are parents/sisters/friend/grand children, total 6 adults 4 children. 

Seller financing won't be entertained because these are both probate sales.  

If you ever want to get ahead in life your will have to act like a grown up adult and pay taxes like everyone else.

I actually designed it for entertaining with a double-height great room and mezzanine that looks over into the main space; there is also an art studio with separate entrance that could easily be a 1-bd.

Again good not only for entertainment but also for workers/jobs. 

Complexity being that my mom is retired and doesn't want ANY income for whatever financial planning reasons and she doesn't want to do the work, but she's liking the idea of keeping the wealth in the family and we've had a very good financial relationship for my entire adult life.

I did have one lender entertain the possibility of 15% down but we haven't yet gone through evaluation of the deal and company together and no where near underwriting.  

(renters is key word, I think there's more of an appeal for homeowners and those with families - I'm making an assumption that the majority of families in southern NH with an adult commuting into Boston are buying and not renting, but please correct me if I'm wrong)  To me I think the draw to southern NH needs to come from growth in southern NH (such as the tech you've mentioned), or growth north of route 3/95. 

Now, if your PM missed a history of evictions or didn't check all adults who are living in the unit, that's certainly an issue.

Better than pissing away their incomes @ the local bar..............................it has been said high proportion of these 2 occupations have problems with adult beverages.
