I understand vibration cannot be dampened, but I think voices and music would be dampened by this method. 

I love the BRRRR method, having scaled my real estate portfolio from just 2 units to 18 in 12 months (From 2 units to 18 Units in 12 Months), and later from 18 to 60 units in the early months of the COVID-19 pandemic (18 to 60 Units During the First 9 Months of the COVID-19 Pandemic).

Then determine your method.    

It's not the most efficient method, but it works and as you grow with scale you can upgrade systems

I am interested in multi family rentals, single family, and utilizing the BRRR method.

This can be really helpful if you're planning to scale up your portfolio or if traditional financing methods don't work due to self-employment or limited traditional income.Bridge Loans – If you're leaning towards flipping a property or doing major renovations, a bridge loan can give you short-term financing to get the property ready for sale or refinance.

When you start to feel like you are starving for real estate, you are fodder for everyone out there who wants to wholesale you a dump on seller finance or some other quick method that won't work.Your only job if you want more real estate is to create more capital for yourself and more equity in your current home.

I would focus on flipping to build more capital; however, if the deal allows you to use the BRRRR method then I would refinance into a DSCR loan after the rehab is complete.

Always good to start with the tried and true method to get your feet wet.

Reading all your posts on BP helps me to indirectly get to know you, and I really like your NO BS style and high level of knowledge about the topics you post about.ZCF is pretty advanced financing method, for me, and I like the concept for the exact reason you mentioned, I just get nervous about anything that is highly leveraged and then the phantom income in 7-12 years, risk of the asset going dark if it's a STNL, etc, etc...I have a basic idea of the pros and cons of the ZCF structure, but, I need to learn more and/or have someone hold my hand through a detailed analysis of how it would apply to my specific situation and how the cons are mitigated.Hows your schedule been lately?
