Also the deal size you are talking about.If you have say 100k to work with then small balance retail condo,office, or say an old town building might work for 100k investment.Those type of properties you have to work harder for yield.My clients tend to buy properties in the millions to tens of millions in price so cash flow is a consideration but secondary usually to passiveness of the asset, equity growth long term, and high quality location for wealth preservation.   

This is over sized for a stackable but too small for a side by side.  

Your share will be determined by the amount of space you rent in relation to the overall building size.  

Also, I've yet to see, or even hear of any law regarding size of EM.

But, depending on the size of your portfolio (more than 5 units ish), ask your agents to look at this as a commercial policy and be creative and they should be able to give you a few separate options that can save you especially if they provide a shared liability policy.  

Specifics such as square footage, lot size, condition of the house, etc.  

Size is not really a concern.  

cool thats good to hear, however the other side of the story thats not really talked about by lenders is that if you have a lot of other properties in the area you are trying to buy a property "in" then it may be very difficult to purchase an eleventh financed property as a primary residence unless it makes sense for your given scenario.Often times this requires:- a Great LOE - letter of explanation- supporting documentation like relocation letters from employers, LOE's from family members, spouses, marriage certificates, mammograms (show increased family size), etc etc list goes on- your  track record with other properties, like did you buy them as a primary then switch to investment properties (underwriters test to see your past "integrity," with mortgage transactions).

There are a lot of similar sized 3 bed with 2 bath comps in the area selling for around $270K, but not any 3/1s - most flippers are finishing basement and adding second bath.

I use $1,000 per unit for maintenance and up to $1,000 for capital expenses depending on size of building.Bill
