Some of the experts I enjoy listening to enhance my mindset are MeetKevin (has a youtube channel), Jim Kwik (focuses on enhancing your brain), and Andy Frisella (he has a podcast).

How would I go about using Expired Listings to enhance my real estate investing portfolio as I have a real estate friend who has supplied me with them?

Oddly enough permanent makeup, massage therapy, CPAs, and a few other businesses are often clumped in with Dental offices.Would having an Ortho company in a neighboring space be a boon for your business or a detractor?

I know radiators with a boiler are considered more efficient, but removing them and their piping would enhance the usability of such a small space.

My drive to enhance lives through multifamily real estate contributed greatly to our progress.

I would never stay in a hotel again except for a couple things.....1) There are no STRs in the area where I want to stay 2) The hotel may have a pool/spa when I'm traveling to a hot area 3) I want a luxury resort type of stay with swim up bars, massages, etc...I travel almost monthly and I find that STRs are still less expensive than hotels.....getting closer to even , but still less expensive...but you still get so much more....a kitchen for sure, close private parking, maybe a yard....as more people realize the inherent advantages of STRs, I think they will become even more popular.....

Of course what happens if you enhance the property or do an addition etc who is benefiting?

Massage parlor vs massage therapist?

I would second what @Jeff S. mentioned, that true custodians are preferable to IRA administrators.A checkbook IRA LLC is an enhancement on the above structure that is generally more time and cost efficient for investors with a more diverse portfolio.

However, he would like to do "Body Work" or what I assume to be massage or some sort of physical therapy out of our house.
