What is the Lowest Cost Way to Get Equity Out Of Rentals

[William Coet]

Hello,

It seems that the cost of borrowing money is going up.  There are points on mortgages for investment properties (one bank quoted 4 points today) + appraisals + loan origination fees+minimum 20-25% down payment.

Is there a more cost effective way than a conventional mortgage on the property being purchased to use equity in existing rentals to buy more rentals?

For example if there a several rentals that are unencumbered by a mortgage, is there a more cost effective way to take equity out of them to fund new purchases?

Thank you
