Should we set up a business to buy our properties under or should we leave them tied to our individual names ?

For sake of clarity, this $128Bn is cash (or cash equivalents in accounting terms) owned by Berkshire Hathaway, not the individual himself, and really isn't that exciting of a number when you consider a company like Apple, for example, is holding nearly triple this amount in CCE's.

With multiple adults in a household, each person applies with their background check run individually and some screening companies provide a general assessment of whether a person has a high probability of success as a renter. 

My condo cash-flowed, yet the condo fees here are significant, so you need to evaluate each deal for what it is individually.

Like @Dan V. suggested, the "class" is each individual property.

Did you buy it as an entity or an individual?

If one of you alone qualifies for the mortgage, then that one individual can certainly do the refinance in just their name.What sometimes comes up with scenarios like this is each of you is individually fully liable for the mortgage, but each of you only reports half of the rental income.

I'm open to looking at each individual property and deciding if it aligns with my long term goals.

Do the maximum FHA loan amounts fluctuate depending on the individual market?

If you set your sites on Arizona, PM me and I can go over some options.I have considered this and looked into properties that are resort like with hotel management onsite, but individually owned.
