But then again, I’m not experienced in it, so I do need expert advise on what garage size and door size with height to pick.  

There are a lot of details that would be good to know such as size of multi, age, number of units, etc. 

The once-iconic retailer Kmart is closing its final full-size mainland store in Bridgehampton, New York, on October 20th.

I've only done 6 new construction builds ( ADU's ) ranging from 500-1200 but all seperate properties.There are also two other 0.48 acre lots (that were never merged together) adjacent to the current large lot of 3-ish acres to make this a total of 8- 0.48 acre lots when/if these do get reverted to their original size. 

I wanted to buy a mid size apartment because of the scalability.

We are with you every step of the way……..until your check clearsplease do a thorough vetting of any investment you make, at least if it is a size where a loss will cause you concern.   

It seems like that size purchase wouldn't make it worth so would love to hear more on that.I did a 1031 exchange here in Chicago, where we built a ground up single family, but then exchanged into a 19 unit building.

Is it possible for this size of project?

I had a few people interested only after I dropped the price down to $2100/month for a 4 Bed/3.5 Bath, utilities included, and I was the cheapest house in the area for that size on FF (we also allow dogs, which many don't).
