Since he didn’t seem anything like whatI thought of as a “super sales personality”, I asked him how he found such success.

That said, that isn't the kind of action I'm personally cool taking part in or giving advice to others to do. 

I assist clients in figuring out methods to finance real estate, and house hacking is my bread and butter.Something i've done personally and continue to help new inspiring investors do every day.

House hacking will also give you some personal "property management" experience.

Guiding, advising, meeting in person, hours on the phone, discounting on property price and services.Properties appraised for more than you paid, you sold for more than you paid.

We have a person on board with a degree in design, so we usually tweak the floor plans for sight lines and function.
