Do you use your own cash or do you have a lender or investor funding your deals?

If you are selling for 1M after closing costs you could purchase two 500k properties in your exchange and own one cash and a mortgage on the second.

Do your own research, but happy to connect and chat further.  

Just you own money?

You should track your own units expenses as well so when you move out, you can quickly reclaim any expenses or depreciation you built on the personal unit when converted into a 2nd business unit which would then be included on your schedule E.You also write off half of your property taxes, insurance, HOA dues, or any shared expense.

I own property and do interior design for rental and investment properties so I stay up to date from my clients and local events I attend through RE associations and meetups which I recommend.

Currently, I own my primary home and a rental in San Antonio, TX. 

Did you require this or did they just get it on their own?

On another note, we recently had an epic snowstorm in New Orleans, where we own a property.
