I’m looking to expand my rental portfolio by utilizing the brrrr strategy.

What I look for are first number units also if the Utilities are separated.

Pick a few neighborhoods you want to invest in and drive around looking for vacant houses or houses that are in need of some TLC.   

Pick a solid B-Class suburban area.

I have met a few investors who have spent cash on properties that they just picked off the list and Google Earth'd it for due diligence (kill yourself if you do this).   

I would give her only a few days (other landlords can weigh in with Best Practice) to move out, clean, sign-off on ending lease mutually, only pay after inspection of property (and utilities, apparently, if you think she's breaking them) is complete and satisfactory.

I have even seen people short numbers for utilities in the MLS listing.

Martin Saenz - not afraid of failure- they pick up a telephone and call people- understand their value and pay for things to free up time to focus on more important tasks- never stop learning.

Been lurking here for a while to pick up some data/observations on different markets. 

You will have to pay higher property tax and utilities and maintenance will go up a bit but the extra unit is well worth it because you'r essentially upgrading for free.You need to take into consideration the closing costs of selling your house, buying the 3 fam, and mortgage for the new house.
