.: Hello,I have several SFRs that have lots of equity in them and I wondering if anyone used a method of cross-collateralization to pledge the equity as collateral, thus avoiding doing a cash-out refinance or HELOC.

Investors may like the income on the spreadsheet, but the appraiser for a traditional loan won't care.

Is this a common method or not?

If that is your intention the slow flip method is not for you.

This could make sense if you do't qualify traditionally, AND you plan on refinancing again within a year or so. 

You can also use the Enemy Method to check the rates of your competitors.

@Maria Jeanette Using a self-directed IRA (SDIRA) for real estate investment offers control over asset selection and tax advantages, such as tax-deferred growth (Traditional IRA) or tax-free growth (Roth IRA).

If the houses are in decent shape and could get traditional financing do not sell seller finance.

If I did the BRRRR method would this work out perfect?

Many don't come from traditional lending sources.
