It's ridiculously powerful and really help you multiply profits and get additional depreciation on the same dollars.Good luck on what you're trying to do.

But, you could determine a general GRM (gross rent multiplier- sale price/monthly gross rents) for the neighborhood (preferable similar type properties-duplexes vs duplexes, etc) and apply that to each unit's rents or potential rents.

I can always tell it’s your listing on mls when I see the “gross rental multiplier” being mentioned. 

Me and my wife are similar in that she is a multiplier (detail oriented) and I'm a simplifyer (big picture person).

DSCR loans are very easy to figure out.Take the Principal, interest, taxes & insurance and multiply that figure by 1.1 (or whatever DSCR is required by the lender)  (example) The loan costs $1,200 per month... $1,200 x 1.1 = $1,320 - (The required market rent figure if loan costs are $1,200) If the market rent doesn't cover the loan costs, DSCR lenders have no choice but to lower the LTV to make the loan work.

@Tim Lee, your offer should be no more than: Land value, minus tear down cost, multiplied by 70% (ie. same as any Flipper working out their margins, but, based on 70% Land value ONLY)!

I bought aggressive stocks with the $ to let it multiply.

5) Other homes that have sold off the MLS in your town(s) - town offices all have files of sales for each year, some of which will have occurred without being listed and you may find one or two like yours in there.6) Dollars per SF comparison with the comps - take an average $/sf number from the comps you find and multiply that number by your square footage to come up with a number on yours.7) What would yours cost to build today?

When you have that much money, it really doesn't matter how much it multiplies or how fast you spend it.
