I highly doubt a property like this will produce reliable cash flow and consistently carry your debt.

You buy raw materials (junky houses, building materials), put in labor and produce a salable product. 

They are nice romantic stories and certainly produce quality returns.  

If you do a good job it can produce some big paychecks.  

Talk to the agents in the offices that are the top producers and have a large network.  

Of course, over time inflation and rent increases make the investment more valuable and the property will produce a positive return that gets better every year.I also think anyone (like myself) will tell you that gimmicks like no money down and interest only as well as owner financed deals are all meant to favor the bank.  

Any house under $50k and your buyers will have a harder time getting funded than higher priced houses.Most wholesalers eventually transition to buying income producing properties for long-term security. 

My understanding is that due to the market going up, it has become harder to find properties that are producing a favorable ROI.

For future more complex deals when you have to produce a profit and loss statement, it will look far better with good chase reserves.  

It's putting a strain on the producers and giving the takers a false sense of reality.
