The agent will prob know other key players such as a lender, property manager, contractor, etc. 

@Guy YoesThere are a couple of different programs to use to keep track of your income / expenses of which Stessa is one of them.The other big players are Excel, Quickbooks(Desktop and online) and Xero.

Even the big players I know of will do the quick and dirty underwriting in excel to make sure it pencils out, before going into Argus for full underwriting.While it is the industry standard and has a lot of very powerful features, I think it is often overkill, and time intensive to be reviewing deals.  

This should give you some confidence in their capability.

A normal property management company will not be the right fit.Running out of area investments takes time to get the players in place, but if it is done right it can be wonderful. 

Thanks to all.Just to add to clarify my read of your comments - I am all about tenant's quiet enjoyment, just wanted to make sure that code enforcement/issues are not extreme and that handy Landlords are able to do as much of the work as they are capable.  

You are perfectly capable to do a deal by yourself.

Completely understand about being 'just' a wholesaler with no buying capabilities, however we've purchased about as many properties as wholesaled at this point.

I have also been a baseball player for the last two years and my income as a minor league baseball player would not qualify me for a traditional or FHA loan.In terms of down payment options I have enough, but not enough to buy all 6 houses.The owners like the idea of keeping the cash flow as they move to retire, and the idea that they may not need to pay capital gains (they bought these houses in 2009-2015 in Las Vegas $$$), but in order to transfer title and ownership they would need to take care of the existing mortgages. 

I would give them the choice:  1) Lose this deal by X Date or 2) Loop you in with the power players of that other deal, be it agents or lenders so you have direct access to the truth about what is going on there.
