That's all I've noticed; looks like the rest of the math is correct.

Of course, the real math will be more complicated since the valuation of your prop has changed over time, but let's keep it simple.

Here's the simple math for a BRRRR: Buy a distressed property for $75k, put $25k in to it and you are $100k deep in this one deal.

Note: Using 12K seller's credit to buy down the points.More math for those interested:Loan OptionsLender paidBuyer paidPurchase Price$452,000.00$459,000.00% down5%5%Loan Amount$429,400.00$436,050.00APR4.40%4.20%Duration of loan360360Total PMI Paid$0.00$6,082.90PMI0.00%0.16%Total PMI$0.00$675.88Monthly PMI$0.00$56.32Monthly P+I$2,150.27$2,132.36HOA$404.00$404.00Taxes$291.67$291.67Insurance$150.00$150.00Out the door monthly$2,995.93$3,034.35

If you are able to find the right deal and the math works for the property, a private money or hard money lender is going to be willing to help you make the deal happen.In chapter 13 of "The Book on Rental Property Investing" by Brandon Turner, he lists 8 ways to get private lenders to say "yes". 

Getting the math right is critical to getting a good deal. 

@Keith LinneOne more question when calculating your DSC what sort of occupancy are you using in math?

Let’s do some math here, let’s say you bring in $100,000 to invest into an opportunity zone, with these potential savings you could be looking at $70,000 in potential additional returns over 10 years.

I like the math on commercial MF RE, it makes sense to me.

Seems like that’s hundreds of deals away when I do the math ??
