That's $30K per year gross, so $200K is a 15% Gross rent multiplier.

You cannot multiply wealth by dividing it.”

Annual Expenses are projected for the property by multiplying (1) the actuals for the current year you obtain from the seller and (2) the project rate at which the expenses for the property will change year over year.Property Value can be obtained from your realtor or can calculate it based on the comps for the area. 

There is a public use regional airport about a mile from the 4 unit building I'm closing on today, if you fly yourself ;)  Really do think there had already been a lot of opportunity in the area and Foxconn multiplies it's potential, both residential and commercial.

I'm aware that 4 months is probably not enough time to signal consistent rental revenue for a potential investor to justify a multiplier, however I still wanted to evaluate the possibility and seeing if I could sell it.
