I'm leaning toward buying a single or double family home with the intent of renting to others - not sure about short or long - i guess it depends on the deal and how it goes? 

The cash flow is great, but I am looking for a lending source---private or a financial institution---to buy many more like these---they need to be in small cities though.Property management is not a problem, since they own the house and will fix it up themselves. 

@Charles Burgess To be honest with you, the chances of you buying a lot and building on it for less than the cost of buying an existing property are pretty low.

The product appears to be more than just a coating as it goes on in some depth, then hardens into a seamless layer. 

Outside of real estate, my day job is a Product Manager at PwC.

If the value goes down the tenant doesn’t buy or renegotiates and you lose.

If you were me, would you be looking to buy now or waiting to see how the higher interest rates and end of the pandemic (hopefully) impact prices?

Buy with seller financing with terms that allow a 48-month principal payment of $150,000 and you've achieved your first question.

Can anyone recommend any good note buying marketplace forums for buying/selling. 

That way we can buy homes already placed in parks and make cashflow + a down payment and don't require a real estate license.
