Will these be motivated leads or simply contact information of sellers who are "considering" on selling? 

It has also been suggested that I use HUD financing since I would only need 3.5% down payment and the seller could assist with closing costs.What are some possible options that I have to make this duplex deal happen with limited cash reserves?

In order to keep that heart, you need someone who understands that love you have for the home you either want to live in or need to let go of.I am a Realtor who is always in search of clients - Buyers, Sellers, what have you.

The sellers will need proof of ability to purchase when you make offers. 

I would be purchasing three duplexes and possibly a SFR using seller financing.

This means you must acquire the replacement property under the same legal entity that was the seller of the relinquished property.  

I was actually wondering who claims the mortgage interest for tax purposes. is it the seller i'm buying from since the loan is still in their name?

Currently have it on a 3 year carry w the seller.

Are rentals in that area in demand?

Once I won it I had 48 hours to get back to seller with signed contract and this was not nearly enough to get a contractor in even if I paid him $350.
