When was the last time my coach/mentor/instructor personally closed a deal? 

Personally I look at that as the easy side of putting value to a  BRRR or fix and flips.

Do you have a 501c3 that you operate under (and rent the house from yourself), or do you purchase homes with an LLC or personal name, and run as a regular business? 

But I find from personal experience and from my buyers' Airbnb experience that it's a bit of a hassle trying to get guests to rebook at the new listing.I don't know how strict Joshue Tree is at enforcement, but in Denver and Colorado Springs here, you could probably get away with an STR listing for three months without the license.

This is one of the best personal finance calculators I have seen. https://docs.google.com/spreadsheets/d/1oC4gdK5gXIPjyEFTgo3g...

I have personally been the guy who hasn't pulled permits and got caught...by far one of the worst experiences of my investing career.

Spreadsheet sounds like my own personal hell.

Also, you don’t need a business license just to look at properties, but if you buy a bigger property, like a multi-family unit, you might need a certificate of occupancy, depending on the local rules.For business trips, most expenses can be deductible, but if it’s part personal and part business, you can only deduct the business portion.

Just a good person too if you want to bounce any ideas off her. 

If you do decide to do mailer(s), then I would advise you to personalize the card and do a handwritten note.
