.: 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.

I am generally in camp "seldom sell", but in this case my vote is to liquidate.

Find Brandon's videos on YouTube for the "four square" method of analyzing homes and practice.

Additionally, they managed to refinance while the rates were at historical lows (and still somehow cashflow negative ik 😭), so any loan methods that involve changing those rates are not ideal.

Perhaps they invited Jerryll based on his extensive SEO knowledge and did not look into his questionable marketing methods and extremely high course pricing at $5800 and $19,800. 

When looking for a property to purchase, make sure you take this into account. 2) The BRRRR method is really hard to do in Bing, especially in student areas.

Is this a common method or not?

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

That method will increase your ROE significantly more.Also read the BP book on BRRRR investing.

As you know there is no equity in this method, BUT it gives you money to go purchase that equity.
