The experts at BP were my 2nd stop as I wanted to confirm my calculations and assumptions on expected returns were in the ball park.I've been a member of BP for a while and you've always had great input.  

They should be doing a load calculation, taking into account insulation and window type if I'm recalling how it works properly. 

good CoC seems easy enough to come by based on the calculators 7-8% on industrial 25-30% on apartments.

@Rahul Sivaswamy if you use the BP Rental Calculator, it defaults to 5% Vacancy, 10% PM, 10% Maintenance, etc.These are all pretty good estimates, except the Vacancy factor of 5%.

The liability from the DSCR loans will still be calculated on your business tax returns.

Only on rare occasions, when I had exceptionally clear thinking and well educated person (which, I will emphasize, was rare in wholesale or car buying business), I would go into details, break down the numbers, show my spreadsheets, sources of information, calculation and justification for the price I offered.

As it is I paid for some calculator they were supposed to send me but for some reason they won't respond back to me so I thought that was odd in it self. 

I use Rentometer and AirDNA and the Bigger Pockets calculators.

An insurance broker explained this to me in the past as the law of  large numbers which suggests if a a carrier has significant enough exposure in a market the probability of claims arising will be more consistent with probabilities calculated in their underwriting than a when a smaller sample size were to exist.

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.
