Your rental income depends on your tenants remaining employed and paying rent.

If your employer was not owned by you or a family member that sort of self dealing would not be possible.

-the tenant is a friend of mine, and I believe his car and address for employment and bills is still listed at his parents' house a few cities over. 

Paystubs and / or double check their offer of employment with their employer.  

Also another reason people can need to pivot from utilizing conventional loans is their DTI gets capped or they are self employed and thus despite having ample liquidity to conduct the transaction they’d trying to do, can’t document income to the lender’s standards.  

As someone who has hired and worked with many, I’ll tell you that these employment opportunities are great for both sides, just as every business transaction should be.

In contrast, wholesalers focus on quick, off-market transactions, often sidelining realtors, and potentially undervaluing the property to ensure their profit when the contract is sold.2.

In contrast, according to a Yahoo Climate series on how areas are and would be effected by climate change in the years to come ranked Oregon’s Curry County, which is located on the coast, as the top spot on the list of 10 safest places to live in the Pacific Northwest when it comes to climate change risks, and is rated as 20th safest county overall in the lower 48 states.

@Alf Holst another way to achieve what you want is to give preference on occupancy to those employed in town.

I was wondering if there were risk mitigation strategies I could employ.
