There is a meetup that @Charlie MacPherson runs, he'll jump in and give you details. 

Details, Home is Mortgaged for $150,000, Value is higher around $200,000.

Even if you decide to switch the nature of the heating system, you should, and still may well be required, to perform this analysis.A detailed heat-loss model will also help you prioritize and plan improvements to the building envelope - such as air sealing and insulation.A few missing bits of information,  which may assist the BP community to provide you with some helpful ideas, include:size and organisation of the building: SFH, duplex, triplex, etc.

But we have a plan to get there in the not too distant future ... my next post will detail my plan , just thought I should leave something to desire on that front before I dive in :) 

The questions I have relate to the details of the transaction (should the loan amount be the original amount, or the current remaining balance?

In my area, most general contractors will come bid a potential job for a nominal fee ($75-100, applied to the project if you buy and use them) and take as long as they need to come up with a detailed bid.

Dan I tried messaging you but your contact details are hidden.

I'm going to say that I dont think $15k in cash is going to be enough to get you started, so you may have to be creative in that respect to have more available cash on hand, but the lender can give you those details.

You must likely need to serve forms - available on NYC Housing Rent Board's website - detailing term of lease , percent increase, reason for increase etc. 

However, after detailed conversation with Tammy, I decided to trust my heart and go ahead!
