But if seller was in such financial straights to have any risk of doing such, I wouldn't recommend getting into a C4D, there is other mechanisms of potential. namely, assuming the mortgage. 

J F C...I suggested the video to illustrate the mechanics of it, not for people to nit-pick it to death!

There are 1920-1930 vintage properties  with recently updated mechanicals and a new roof and there are the same vintage properties that need work. 

The listing agreement would include within the commission property photos, a set number of “door-opener” tours, some hours of phone/Zoom consultation with a licensed agent to set a listing price and discuss offers, counter-offers, and closing mechanics.

It is mechanically sound with new roof and siding in 2017.

If you can’t quantify risk and don’t understand the mechanics of “weighted” average of expected return and range of returns (standard deviation) then you are at a severe disadvantage and should consider a competent investment / financial manager for your investment capital.  

I'm saying you invest with appreciation on my mind, and make sure you're situating it to remain cash flow neutral to positive via other mechanism.

Make sure you have smoke and CO detectors in appropriate places, GFCI outlets near water, functioning mechanicals, make sure everything is in good condition and you shouldn't have a problem.

Cash flow is a mechanism of leverage(min 1.25 DSCR).If you want to get even craftier, then of the cities you've set your sight on criteria wise try to go in as inventory increases.
