Fat hogs get slaughtered so spreading the risk is what I'm looking to do. 

I get a cheap house and they get a fat check.

Those who choose the first path are smeared with the stench of those who choose the second.I think the difficulty is that a vast majority of people should and do sell their property through a realtor or at least go the FSBO route, and there are a lot of "wholesalers" who listen to the less-than-ethical gurus who tell them the can make fat stacks of cash just injecting themselves in the middle of the sale. 

That is why I like to sell commercial for the fat commission but like hold residential for my passive income portfolio.  

Use the money for some additional projects and keep building that equity pool until you've got a fat 1M commercial line of credit to play with :) Unless you absolutely plan on spending every dollar of that REFI money on primo rentals that you really want- not just stuff you're buying to put the money to use.

(the $250k included down payment, holding period for rehab and closing cost).Ideally I'd love to update electric / pluming / ACs / windows.. but i guess that would have to be put on a back burner for now. 

So instead of a fat upfront payment, I'd want my TK provider to take the same risks I am, that is, his work gets him a piece of the equity, not an upfront fee.

@Robert Ellis I have kind of put Columbus on the back burner but may look at it again.

But, as we all know, the real gold mine truly is for all you fat cat Turnkey Providers!

If its the original 4 to 6" red clay pipe its very likely you have root intrusion every 4 linear feet at the joint.Yes you may have collapsed pipe or fittings.If you lucky you may only need what is called a "point repair".If you got original clay pipe its time to think about  replacing it with black ABS plastic pipe,cast iron or PE polyurethane trenchless pipe.Youll see a world of difference and no more phone calls from angry tenants.The plumber will use a pipe camera with a built in transmitter to see and locate the exact problem area,then they dig things up,cut out minimum concrete remove and replace bad pipe and fittings ,replace and finish concrete ,test and inspect again with video camera.How much work is needed is anyones guess especially in an older property.If you are on a septic your drainlines MUST be in perfect order ,,,if you are on city sewer,,not so much.On the grease issue there is a great product called Bio Clean which is a grain based enzyme which works great but you must use it once a week ongoing.Of course if you get the cooperation of your tenant to isolate any grease or fat and put in a plastic bag freeze it and throw it  in the trash you are miles ahead.Tell them if they do that they wont have any more of this kind of inconvenience.You can only get Bio Clean from a licensed plumber.Hope this helps and let me know your outcome.Dave DoyleLos Angeles
