Even a newer 90s home you should easily be under 10k unless its a private home on land. 

Might have a private airplane hanger next to that airport, FEDEX might want an office-warehouse, where is the best place for the trash trucks to be parked or a recycling firm?

I have a friend how's trying (hard to sell) to sell this house on a dead end private street in natick MA, how can I judge that this house is worthy or not to invest, any investor interested on this location? 

In this current go around in REI after some problems early in my career, I have learned a few lessons - - I only buy in cash or borrow cheap short term cash from private investors for ~2 years- I now mostly owner finance so I do not have repairs- I work with experienced investor/agents who feed me good deals not usually on MLS.

These are all legal tools to help seller sell that has a difficulty with low equity positionsNow if it's not low a equity but it's middle equity like $400,000 house $200,000 equity, most sellers will just pay the cost to sell which are about 10 to 12% of the value of the house when you include everything commissions closing costs sellers concessions and holding costs while it's being soldOver a third of houses out there or free and clear with no mortgages and this presents an opportunity to let the sellers know that if it is free and clear where they can do an installment sale and use their house as a retirement asset with no due on sale risk, own a private mortgage, get a cash flow like an annuity payment, and the cash flow can survive ther death and leave it for their kids or charity
