So far the concerns I have discovered would be things like control of collateral, maintenance requirements/margin calls, and various fees that may be charged on quarterly or annual basis.

That for them to consider it, they would want to order three appraisals, and then the loans would all have to be cross collateralized over the three properties, and it seemed over the top and costly way to borrow $75K.

A home loan is made via the note with a Mortgage/DOT (depending on state) attached as the security instrument, which allows the home to serve as collateral if the note is not upheld.

@Bobby Short Depending on the equity you have on your primary residence you might be able to find a lender to finance the property in CR with your primary residence as collateral.

From what I've read, focusing on equity building would look like building equity in the first property, then once you have some equity built up you can do something like a refi with a cash out, or using the equity as collateral, to put money towards another property, and so on. 

The loan will be on the additional collateral you created.

We buy at a discount and pledge our legal right to collect the debt (a collateral assignment agreement) as the collateral for the private capital loan we take out, which is backed by the value of the real estate securing the 1st loan.  

Without predictability on insurability and risk of the primary collateral being destroyed (which at this point theoretically could happen anywhere) as it’s January, and would you believe in 2023 that 71K thousand square miles of northern Canada burned 5% of the entire Canadian forest with billions in damages? 

@Rae Chris, finding a "0% down" loan is hard, if not impossible today, even with your first property as collateral.  

Yes you could do a bridge loan or cross collateralize the property - we do those all the time.
