When current lease agreements or market rents reported on Form 1007 or Form 1025 are used, the lender must calculate the rental income by multiplying the gross monthly rent(s) by 75%.

If you're year one, then sure, multiply by 12. 

Then look at your time horizon for wanting out of a 2-4 unit and multiply... i.e. it's $1000/month to rent a place, or it's $500/month after you rent out the other units and you really want to be out of the 2-4 unit neighborhood in 3 years... 3 years (your time horizon) * $500 (the difference in renting vs owning) * 12 (since it's monthly) = $18,000... that means it's $18k better to buy the place.The numbers are all fictional, but the process is not.

I’ve started looking at some private deals and the terminology is daunting.. preferred vs common, IRRs, equity multipliers..

I have experience with private equity and commercial M&A where we use an EBIDTA multiplier to value an acquisition.

He's projecting unemployment to increase from mid 3s to high 4s, which represents 1.3m to 1.5m job losses (he sticks to the % unemployment rate, but journalists and myself keep multiplying by labor force participation rate to express it as a number of job losses - he has never "corrected" a journalist for asserting target job losses to be in the 1.3m to 1.5m range, so both he and the journalists agree on the number, JPOW simply chooses to use unemployment %, while journos use unemployed persons in the millions rather than a %).

Multiply that average comp square foot rent price by your property's or room's square feet to get a comp rental price.   

Capital Calls ( but we currently see this as a better option than forbearance)Come up with your estimated negative monthly cash flow then multiply it by 3 times and that is your capital call.

Now multiply the number if piers by $250. 29x250 = $7,250.Now add $200 for permit & $400 for Engineer's letter (yes, both of these are required by the City). 200+400 = $600Total foundation price = $7,850.

So if we have $75,240 in annual income, multiply that number by (1-0.45) 0.55 to get an estimated NOI of $41,382.
