It would be very good to hear from some executives at Baselane, Hemlane, Hospitable, who have tens of thousands of landlords across the country, share their insights into the subjects @Jamie Petraglia is asking about. 

If by real estate business you’re implying you have little or no money to invest but are contemplating using one of the guru inspired methods (subject to, “wholesaling” , fix n flip) to create cash flow, I’d encourage you to do research on the true success/failure rate of people who engage in these endeavors, the amount of money the successful operators spend monthly on marketing, and the real time commitment and knowledge and experience necessary for success.  

Limited Regulatory Oversight: Fintech companies that operate without a banking license may not be subject to the same regulatory scrutiny and consumer protection measures as traditional banks.

In fact, it’s a LOT easier to find a good / great below market deal if (1) you offer all cash, quick close, NOT subject to financing and or (2) the property is one in which obtaining financing is difficult, if not impossible.Another example of where low DP is not preferable is when we syndicate property purchases.  

For example, if you find a distressed seller you might be able to take over their loan using a "Subject-To" strategy and inherit a loan at a 3% interest rate!

Nickerson added “exchanging” real estate to upgrade to larger holdings without paying capital gains tax to his formula, and a number of other books were written about the subject in the next 10 years.  

Buy BP's books on creative financing, zero down, subject to,  pre-forclosure, even short sales.   

So either way you do it you will be subject to those costs and for the first years majority of your payment will be applied towards principal. 

This is a subjective question, and everyone will have a different answer to the same area.

Appreciate any knowledge and advice on this subject!
