Hypotetically, if I use IO loan only, I would lose money as aggregated principal is much less in IO only product.But since i use 10YARM then I made lot of money, even better than 30YARM.But now things are changing.

this is me and my partners 1st deal we got 14 days to find a buyer/ or find another exit strategy.My question is, how can me and my partner work with a private lender to get this deal closed if our buyers we made contact with are not serious about closing but we know there is money to be made in the deal!?

The skies the limit especially if you have a house that could potentially be made into a duplex. 

Specifying your requirements will enable you to focus on homes that meet your objectives and help you narrow down your search.Finding the ideal property may be made easier by using a variety of sources, including direct mail campaigns, real estate brokers, wholesalers, networking events, and internet listings.

Specifically, it sounds like all interest payments made are fully deductible because, in this case, the individual unit's balance cap does not apply (because it is grandfathered) and the underlying co-op mortgage's principal balance allocated to the specific unit is below $750,000. 

They come on the market occasionally but usually get snatched up pretty quick and always seem to have already had a deal made before they hit the MLS.

Jason's comment is spot on, IMHO she should find a very good insurance broker, they're allegiance is to the customer.

What made you interested in investing in this type of deal?
