@Brian Turnbough Any improvement to all units adds value times six and the SFR doesn't have any such multiplier; just dollar for dollar.

@Kevin Thomas You definitely want to nip this in the bud as rodents tend to multiply and their feces can cause health issues if it becomes an infestation.  

The annual column is only multiplied by 12 to create the annual numbers, maybe this is incorrect.

Property taxes and insurance premiums vary way to much in different states for it to make sense to me to use it.If you're asking about what kind of rule of thumb to use to determine if a property is worth further investigation, I personally use the GRM (gross rent multiplier) rule of thumb, because that's what I was taught. 

If you publicly announce your policy on income is rent multiplied by the variable and stick to it you are not discriminating.

As your business grows, if you do not have this system, your problems will only multiply.

On that initial downpayment of $10k, multiplied by this ratio, it means that about $7100 is recognized gain. 

Short of finding a way to multiply my income drastically, we will never touch these student loans.

You can then multiply that figure by 70.

I am too much of a self RE investor doing my own thing than to handing someone money to multiply for me but not like there is anything wrong with that strategy.
