My only concern is that the time on the market is around 70-100 days. 

It would not be owner-occupied so my concern only goes as far as the area not deterring potential tenants from wanting to move in.

Lots of BS excuses and finger-pointing at their hired out Accounting Team for this.My biggest concern now in terms of this one investment is that they are way over-leveraged and are in a position where they will need to refinance soon which will likely result in negative cashflow with interest rates where they are at.   

My only concern is that I am under a work visa, which can be renewed, however I am not sure if for the lender that would represent a risk to have a loan for let's say 30 years.  

@Tim JohnsonThere are essentially two ways (and a few variations) to purchase this deal, depending on how the owners are selling it:As a going concern:  In this instance you are buying the business, so it is the business you evaluate: assets, liabilities, revenues (historical: 3 - 5 years), operating costs (historical: 3-5 years), future financial projections, goodwill, etc.    

While this drop might seem concerning, it also signals opportunities for buyers to find value in the market.% of Original List Price Received: Sellers received 96% of their original list prices, down slightly from last year.

He claimed the only way to place a lien on another person's MH title is to have the owner accompany me to the DMV and we both would sign a specific form, in other to place the lien.I promptly informed him that, in cases of collections and back rents, nobody would willingly allow another person to cloud the title of their mobile home!  

So longevity / durability is still a slight concern there.  

I can understand your concern of not wanting to lose your tenant due to a rent increase.

After James let me know and I called the cops to report Jame’s concern for Steve’s well being.
