@Josh West I think there are some awesome replies in this thread; I think @Rene Owczarski and @Bonnie Low hit the nail on the head. I've put a few of my thoughts on the topic below that I hope you will find clarifying and thus helpful.
One of the more, if not the most appealing aspects of the BRRRR strategy is the concept of 'Infinite Return'.
Josh, you provided an example above that is as follows;
Purchase price: $500k
Rehab: $50k
ARV: $550k
However, as @Rene Owczarski pointed out, if you sell the property in this example, there is no profit for you! You put $550k in (excluding financing and other costs for simplicity) and got $550k out (assuming you sold the property at $550k).
Let's use a different example where we can see the real 'magic' of Infinite Return and the BRRRR strategy at play.
This example will be one where you find a severely undervalued property and do some work that adds some, but not a ton of value to the property.
Example:
As-is value of the property: $200k
Purchase price: $120k
Rehab: $50k
ARV: $270k
Initial hard money loan at 85% LTC, or $144,500
'Cash-out refinance' at 70% LTV, or $189,000
Okay, let's break all of this down, as the "cash-out refinance" is really where the magic happens. However, in order to get to the point, we need to cover the steps leading up to it.
In this scenario, you found a heavily discounted property; the as-is value of the property is $200k, and you are buying it for only $120k (what a steal!). In accordance with the second 'R' of the BRRRR strategy, you rehab the property, and it costs $50k to do so.
The total project cost is $170k or the purchase price ($120k) + rehab ($50k). So that you didn't have to carry the burden of this cost entirely yourself, you found a rehab lender who was willing to lend you 85% LTC (loan-to-cost), or $144,500. At this point, your equity, or money in the deal, is $25,500, or simply $170,000 (the total project cost) - $144,500 (the rehab loan)
Now, after you've finished rehabbing the property, it's worth $270k (the ARV). In accordance with the BRRRR strategy, you rent the property out to a suitable tenant and you wait a few months before you go to a new lender (oftentimes a bank) who can offer you a long-term, cash-out refinance.
Now remember, you've still got a loan of $144,500 from the rehab lender, and you need to pay that off. The bank (or other long-term lender) offers you a 70% LTV (loan-to-value on the after-repair value of the property) or $189,000 loan.
Now, where do the proceeds for this $189,000 loan go?
Well, a portion of them, $144,500, goes to paying off the rehab lender. The remainder, $44,500 ($189,000-$144,500) goes into your pocket.
So, you had $25,500 of equity in the deal, and now you are receiving $44,500 in addition to owning the subject property.
This is the magic of the BRRRR strategy, and this last point is what investors refer to as 'infinite return'.
You no longer have any of your own money in the deal (you had $25,500 in and you got $44,500 out), and now you own the subject property.
There are a couple of key points or takeaways;
1. You need find value or create it. You can buy a property at a steep discount, or you can do work that improves the value of the property above and beyond the cost of the work. In other words, you can buy a 100k property for 50k, you can do 50k of work that adds 100k of value, or you can do both!
2. You need a rehab lender and a takeout lender. The latter will allow you to cash-out refinance, which is where the infinite return happens.
3. The BRRRR strategy is special because, when executed effectively, it allows the investor to get back all of the equity he or she put into the project, and still own the subject property at the end of the day.
Hope this helps!
