Recently I bought a retail center and that deal has been making me think more about if it would be wise to set up a separate management company for all the properties. 

Both approaches fail because they forget the most important part of the deal: EMOTIONS.

Best advice: don't get emotional about a deal.Found first deal on MLS, but have found stuff on FB, Nextdoor app, and even yard signs! 

Sellers can feel your energy—let them see your passion for finding the best solution for their situation.Have Empathy: Selling a home can be emotional.

No emotion.

our first baby is officially on the market and i have mix emotions but more happy because im excited for the next chapter !

I take a picture of their driver's license.I ask for phone numbers that accept texts and any alternate land or business phone numbers.I ask for the names and birth dates of anyone under 18, and ask if there are any service / emotional support animals, together with their names and breeds.I also ask for personal references, previous landlord contact info (and length of time there), employer contact info (and how long there, together with earnings), as well as the name and contact information for their manager / boss.

Under federal law (ADA and FHA), true service animals and emotional support animals are exempt from pet fees, deposits, or rent, but the tenant must provide proper documentation if requested.

It is big enough to build at least 2 separate ADUs.
