How would you calculate these costs if some of the houses are almost identical but in different markets? 

In this case it covers added utilities and wear and tare.I also recently acquired 2 "alleged" thieves who stole from a local store and got shot by the police after they attacked him twice. 

Let's consider another possibility.What if she keeps her home, and does a cashout refi at 4% for 30 years of 75k, and uses that money to buy 3 other identical homes with identical rent, with a 20% downpayment on each (5k for each deal goes to acquisition costs) at identical rates and terms.Now she's got more expenses (about $1500/mo in debt service and more money in other costs), but she's got 4 times the income.So let's go back to the scenario where she's earning $1000/mo/door gross rent.

During this process, you will have to submit an application form together with all the supporting documentations (such as a photocopy of your Identity Card, pay slips, EPF statements, booking receipt and etc) to the Bank and the Bank will assess your credit profile to determine if they want to approve or reject your application.

Congrats on getting a multi.I have two buildings on the same street, they are mostly identical, one building has washer dryer hook ups and the other doesn't.  

But, then I see a nearly identical unit in the complex for rent for $650.  

you may not get your money back.. .usually thieves are not good savers.

It's part of a community of about 20 identical 4-Plexes.  

Just got word this morning that my offer on an identical quad on the same street was accepted.  

The two rooms at the top of the stairs are identical.
