If I don't get the scholarships and grants at this time that I do now, then I may have to look into getting student loans to cover about half of tuition to minimize debt after college and damage to my nest egg.Assuming I'll still have a roommate at this time, I should make enough to cover rent with my current job at the college (which is minimum wage and limited to 20hr work weeks), but it will decimate my free cash flow for sure.Since I graduate this year, I will also be applying to potential employers to secure a stable career if I haven't found employment already.

I see... so essentially if you want to find a "general" price per unit (not taking taxes, insurance, etc into consideration), you'd take the current rent amounts and divide it by the percentage (converted to a decimal obviously) and get a rough idea from that.

Amy divides 669 by 2,076 and obtains a decimal (rounded to at least three decimal places) of 0.322.

This is because if the PITI is greater than the Self-Sufficiency Rental Income, then the resulting decimal will be greater than 1.

"You're decimating our community!"

Its rent/purchase amount  convert decimal to % 3400 / 480000 = .007 (percentage in decimal form) x 100 = .7% This is not a true analyzation, but many use this as a reference to determine if its even worth analyzing depending on their criteria.

First, (forgetting the absurdity of the decimal), a vacancy of 1 month means you will have to find out, clear out, list, interview, decide, collect rent, and prep for your next tenant...in 1 month. 

I l know she did all this work but in the process she decimated her numbers by evicting.

My CAPEX and maintenance budgets for a partial year 1 and full year 2 were decimated, leading to a lot of unnecessary stress and painful situations.Set aside that money now, and either be glad you did or thankful that it potentially won't be needed.I'm sure John can help you with those estimates, but this is one semi-newbie investor to another with probably the only advice I'd go back and give myself buying my first true rental that I didn't already think about or know.

Again  NOI/Cap Rate (in decimal form) =Value (based on Income Approach)
