However...the cash flow would equalize MUCH sooner than 42 years with this approach.

They'd be a great resource for finding you deals.If you do want to approach a flipper to get the deals that they don't want to pursue then maybe you can offer them a small finders fee for each place that they pass you, or at least each one that you close on.Best,Paul

@Mason LinggiNot to be too blunt, but the likelihood of you getting any response from this post approaches 0.

These are the questions I would ask as an agent if you approached me about working with you. 

I would use your access to the MLS and deep search past Multi Unit sales back 20 to 30 years and approach them to see if you can work out owner financing to purchase if they are ready to sell.

How do u approach people?

Because the financing is different for buildings with more than 4 units, as you may already know, you can't really use a per-unit price on a 4-unit and extrapolate to a 5 or 6 unit :(Instead of looking for comparable sales, you usually end up having to apply a market cap rate to the net income (NOI) of the property, which appraisers call the "income approach".As for what's a "market cap rate", well that's about as much art vs. science as (in some way) choosing good sales comps are.For a B area of Providence I think you'd be safe using a 5% or 5.5% cap rate, but if it was an A area like the East Side you might want to go with 4% or 4.5%.You should also ask around as I certainly haven't done any market survey of cap rates.
