Yours question is a little confusing. Are you asking what are the Advantages/Disadvantages using cash in the BRRRR strategy? Or just using the BRRRR strategy versus other strategies?
Just so you know I currently only do BRRRR deals. I rarely use any of my own cash. I primarily use a Private Lender for property acquisitions. I use a HELOC and personal LOC for the Rehab, Holding and Closing costs. I do maintain a sufficient cash reserve to satisfy Lenders.
I like using this strategy for several reasons.
1. I do not have to wait until I save enough cash for new acquisition down payments or to complete Rehabs. In other words I can grow my portfolio quicker.
2. I can purchase properties at greater discounts.
3. the biggest advantage is the return on my money. Most deals I get infinite Cash on Cash Returns. Not 2%, 5%, 12%. INFINITE! That means by the end of the process I own a like new cash flowing property for free (so to speak).
The main disadvantage I guess would be the increased debt. But that is an acceptable risk I am willing to take.
I currently do not have problems finding refinance lenders.
I am not concerned about appraisal being too low. I'm confident my team gets the ARV/Appraised Value pretty close. I include a buffer amount in my analysis to compensate for Rehab cost overages or lower than expected appraisals. So far it hasn't been an issue. That doesn't mean it can't happen in the future.
Not sure about your lower holding cost.
