Honestly, I think you're estimated expenses are a bit low.

This seems unrealistically low for a 40 unit property.

Note you must be an accredited investor to participate.A con that turn some people off DSTs is they come with higher fees than out right owning a stable, low maintenance property; however based off what you described DST fees are far below what you are currently paying. 

If I was the buyer's broker, I would have checked myself to protect my client.If they had, then they would have found out it was not a three family.Its a valid point.In NM, our zoning / city doesn't post # of units publicly, only high density residential or low density. 

Quote from @Bonnie Low: I love seeing your company's growth @Allen Duan!! 

DSCR loans are not that low and regular hard money loans will be in the double digits.

I have lumber liquidators, home Depot, Lowe's, and who knows what else near me (central CT).

Avoid leading with a low offer or mentioning how long it’s been listed.

It looks like you are right to be concerned about the low season as occupancy drops below 50% for most of the year  

Locally my observation is that the need is more for low income young and working vs college student.
