Additional question would be, can the SMLLC build the house at a discount (taking losses for the business)?

The key to a BRRRR is buying deeply discounted properties and/or adding significant value through renovation.

If you know what you're doing it can be a good way to acquire discounted properties.

I have a couple timeshares i bought at a tremendous discount.

Infill lots in the city or recreational lots in the rural areas.. either way you need to buy them at deep discount to make this work. 

In fact if you start discounting vacancy, cap ex, insurance, taxes, etc.

I'll take all the discounts I can!

If you're selling a home in Maryland, you can use a discount broker to save on realtor fees.

You can be ready to acquire properties at a discount from those forced to sell due to cash flow issues​.Focus on Cash Flow Today: With BRR"R"RR, you are prioritizing properties that cash flow from the start, making your investment stable and less reliant on speculative future appreciation or short-term market shifts.

Youll be more likely to buy at a discount and don’t need the property to be move in ready to purchase.
