The investment that I was exposed to requires that one be an accredited investor to invest.

@Natalie TreasureIf you are planning to "flip" properties, you are not going to qualify for a high-ratio mortgage ... you might pull it off once, perhaps even twice, but the lenders and insurers will figure it out by then.That said, you can obtain a high-ratio mortgage (90% LTV) for a second home ... intended for vacation homes or a pied-à-terre closer to your place of work, lots of folks use these to purchase a house when their kids go to university or their first rental property.  

Most have to be accredited but seems many CA investors hit that hurdle in my experience.  

All my units near the university campuses rent fast, 2 weeks or less if priced correctly and right before school starts, otherwise during summer it may sit for a couple of months. 

Is the college/university ever going to go away?

Hi @David Hutson, if you're an accredited investor and you decide to 1031 the rental you're selling, you might consider reinvestment into DSTs.

I graduated from Northwestern University in 2014 (go Wildcats!)

What are the best university towns? 

I am currently a student at Freed-Hardeman University in Henderson, TN.

If you listen to the 2 podcasts dedicated to mobile home investing, or take the MH University course, they all seem to agree that 30 spaces is their minimum, and 50 spaces is ideal for an on-site manager.
