To add to what @Bruce Lynn said, I was working a deal recently in Dallas and I found that there are many restrictions on renting by a room, mainly because you will become a hotel at some point (not sure about the restrictions) in my case I found that the subdivision had a restriction to rent one room. 

I was interested in that community and heard good things, mainly proximity to Disney and amenities. 

If they have a higher income, they are likely living large and accumulating more debt; but as a landlord your main concern is will they pay the bills and take care of your rental.

The market has corrected, and unfortunately, this means that the value of your investment has taken a hit.The main issue is that these properties were purchased at a high basis, meaning you bought when prices were inflated.

Mainly because they have more to manage so they are not as dialed in on every property they manage.

My main concern would be using HELOC on personal residence to make first real estate investment, not as concerned with the Roth/IRA but still don't want to make a big mistake on the first one. 

All of the elements of an easement by necessity (or prescriptive easement, depending upon the facts) would need to be satisfied... read SD case law to find out what would need to be proven.

*Newbie Investor I’m currently looking to buy a long term rental with minimal renovations in North Carolina and chose Fayetteville as my main area of interest.

The main difference right now that you would see between a primary and an investment property is the fees. 

I am converting my garage (attached to my main home) into an ADU in California, and I will rent out the unit when complete.
