I have 2 rentals and I can't imagine multiplying the promises, excuses and stories every month by 12 to handle 24 units.

My holding period is around 3 months, so I multiply points by 4 and then add that to the interest rate to figure out my effective annualized interest rate.

Yes, a broker could just focus on making sure he got the most out of the one transaction, so he would prefer to sell a $300k house over finding one for a fiipper at $200k, but that flipper's house could be, under my example, a total of $550 in sales, multiplied by however many times the flipper reinvests and flips, instead of just that $300k one time deal.

No multiply that by 2.

For those of you not good with excel, go to block B4, go up to the line you can input your numbers and change the multiplier to whatever your area's RE taxes are.

Now with commercial, comparable sales factor into the income approach anyway, with the Gross Rent Multiplier (GRM) used for the income approach coming from comps, so I think those two methods are rather redundant most of the time with a commercial appraisal.

Now I also take into account idiosyncrasies of the house and the neighboorhood, and whether the house is under or over built, but initially it comes from an average sold per square foot number from the area, multiplied by my square footage.

That being said, it is imperative that you understand the particular areas average operating costs including taxes, insurance, management, maintenance, utilities, etc.For a quick financial rundown on a property, I take the gross rents, subtract 10% for vacancy, multiply that AGI by 60% (40% oper. xpense) which gives me an estimated NOI.

As a rough estimate of value you can add up these rents and multiply by 10.

If you want a "quick and dirty" analysis then just take the total monthly rent ($900) and multiply by 100 ($90K).
