With the current mortgage rate constraints affecting how many buyers are willing to enter the market we are seeing a lot of borrowers have success with the BRRRR strategy with plans to sell in the next 3-5 years when interest rates go down.Researching potential LTR and STR rental amounts and seeing if holding for a few years is a viable option is a good analysis to do well. 

Helps with your debt to income, better opportunities at cash flow, and typically requires less down to purchase.In regards to challenges, I usually build in an extra 10-15% to deal with things that I can't see behind the walls, including dry rot, electrical or plumbing issues, etc.
