It's no guarantee but it's a good place to start.

Husband is interested investing in them, but I cannot find ANYTHING online about them no reviews ANYTHING!!

That’s how I got started—with little to no money out of pocket.

There are no laws restricting mark-to-market rents. 

If you control how they perform tasks, set their hours, or provide tools, they should likely be a W-2 employee, requiring you to withhold taxes and comply with payroll regulations.

These are the top three features I always keep in mind when evaluating a potential property:1️⃣ Location Matters: Properties near attractions, with great walkability, or offering something unique—like a waterfront or mountain view—tend to perform better.

Below is the link of the property:https://www.loopnet.com/Listing/927-Dixon-St-Tiptonville-TN/...No idea why it would be listed in the title unless the owners took some kind of government incentive that requires them to only lease to section 8 tenants.

. - You have no recourse against an agent or PMC once you pay them for the placement and it turns out to be a terrible tenant:(If you have the time and network and post here for assistance, it's always a good idea to learn the rental business from the "ground up".Of course, one mistake can also cost you thousands of dollars.

one of my clients that has a pretty big PM company.. had a unique way of doing this.He offered 50% of the first months rent or 500.00 minimum.. he would have 4 or 5 agents at the weekly meeting handout the list of vacants .. each of them would go place a sign in the yard and first come first served.. he found that potential tenants would call the first sign if no answer they called the next one until finally someone answered.. it worked pretty awesome for him. 

This couple has no kids.
