I currently have a contract on the property/land and seller would like to close by the end of the month 29Sept2016.

I know that areas near Park Ave, and University of Rochester have strong rental demand, but I was hoping to speak with anyone who has other areas that are relatively safe for the city and can attract good tenants for cash flow positive rent. 

Maybe seller financing or ...

The lender will probably not object, since it will assume the seller has implemented an estate planning device.

You can identify the two highest retail price ranges, in greatest demand, per zip code where you can list the rehabbed property.You can use the Realtor to help you find deals and also use Wholesalers.

I have a seller that has agreed to seller financing, now what?

My only problem is, after submitting an offer that same day and questions about the seller financing they offered, we heard crickets from the broker. 

If you want to really check their records, go with a broker and they have a broker program and can tell you exactly their real sales volume, and if it comes from buyer's or seller's sides.  

However, I seldom got such information from my buyer's agent (i.e. if it can be found via mls)and I tried to ask my agent to get those documents from the seller's agent.

We are looking in Beacon, seems like demand in that town is only going to keep growing, you feel otherwise?
