I'm leaning towards the buy-and-hold approach towards investing, for some good, reliable cash flow.

@Felix Sharpe-- Here is my strategy ... a combination of the below approaches:(1) Market Approach: Review rental prices of comparable properties currently listed on the market.

Nice relaxed way of approaching this business!

I am just wondering how to approach the seller.

I am in contact with their agent and working with my lender to determine a possible approach.  

There's a lot to learn...where to find NODs, how to search your county records, how long it takes to foreclose and how much time you have to contact your potential sellers, how to approach lenders if you need to (get a specific POA from the owner), what happens if the seller decides to declare bankruptcy, what to put on your contract, how to get and record the deed, if there is a second can you work a short, can you work the BPO, etc.
