The BRRRR strategy can be applied to a single property or multiple properties. In the example of one property, it may look something like this: Buy an investment property with all cash; renovate your new rental and get tenants in quickly so you start collecting monthly rent checks from Day One (or close as possible); refinance that mortgage on your new building when rates are low or give yourself some equity by selling if they rise too high; repeat starting at “Renovating” until you have four rental units.
Repeat these steps for each additional purchase and continue making money off them! Check out this article that explains the ins and outs of BRRRR Financing and how you can do it.
