With contractors hard to find and materials costs still elevated well above where they were pre-pandemic, BRRRRing is not nearly as safe a bet as it once was, especially not with a ticking clock of a hard money lender.I've noticed on the podcast lately they have started saying things about "Just getting in" and "not trying to find the perfect deal", but just something that "gets you in the game"...

Alternatively, hire a company that utilizes dust collectors with the grinders.

So idea is that I would post my favorite deals and some information / material there.

From what I read, it is basically mandatory to replace knob and tube wiring due to the degradation of material, and no grounding.

Hard to believe 62 square feet could make a material difference. 

Time costs, material costs, regulatory costs and mistake costs.

As an estimator in the construction industry, I second @Rodolfo Goncalves; inflated material prices and labor shortages has made development very costly right now.

As a builder, you should lock in material prices under a contract with your supplier or put a stipulation in the sales contract that pushes material increase expense on to the buyer. 

I've seen quite a few alternate lending products that are pretty competitive with MFR loan pricing even on gov backed loans.

Alternatively, I could put tenant interview as one of the contingencies.
