Pretty weird huh since obviously I’m a scumbag wholesaler in your opinion.You put in as $0 as E/M and then you can just walk away if you can't get a buyer.I close on EVERY deal genius.

While this is a lot of money, most any mid-career professional likely has that available to invest (maybe not liquid today, but in general).  

Lenders will use your tax returns schedule E to calculate your monthly rental income.

then MLS feeds to all the SM sites and agents can filter through the responses or if it my own property like here in Oregon with our subdivisions I handle the first calls and then qualify them once done and appointment set hand it off to the closer ( my wife )  If I get a ton of E mail request for info I just tell them they need to come and look first.

If you need the cash liquid, that changes the decision 

It's all fun and games until there's a liquidity crisis.

The first year is probably the most crucial year, as you will need to calculate the cost basis in your rental properties, which will influence your depreciation expense on Schedule E.

Any list you can pull for a few bucks has already been hammered by hordes of investors before you.Not saying this way can't work, but I recommend a different path...I prefer to focus on sellers who have a reason to sell but who require some effort and skill to identify.My favorites are #TiredLandlords, namely owners who have filed an eviction lawsuit against their non-paying tenants.Many of these folks are through being in the rental business and are open to hearing about a way out.Even better, #TiredLandlords are ideal candidates for seller financing, since they don't need the sale proceeds to buy another house, PLUS they are already conditioned to receiving monthly payments over a period of time.

I have some favorite marketing tips that might help you. 

Other one I did its just moving along fine no worrisome e mails no hints of cash calls superior communications etc etc.
