Do you want to work on the residential investment side, selling distressed assets, and small multi-family, or do you wan to work as a commercial agent, either selling commercial property or leasing commercial space? 

I'm not in the STR space, but would be interested in what they offer.Regarding Esri, do you use their enterprise subscription?

The warehouse space needs to be converted into self-storage.

If you go over 3600 sf you will need to do a fire flow test and depending on the results may need put in sprinklers , although it doesn't sound like you will be getting that big.You need to park both units (duplex or main house+ADU), each unit needs 2 off street parking spaces for a duplex; main house needs 2 but an ADU only needs one and it doesn't need any if it is within 1/4 mile of an Imagine Austin Corridor (Burnet or W Anderson both are I believe).Also a duplex needs to have a shared wall that is at least half the length of the depth of the building (the wall can jog and zigzag, but the total length has to be >.5 of the overall depth front to back of the building).  

I'm new to the commercial tenant space and was just looking for any insight and best practices to make the transition as smooth as possible.

Transaction volume in the commercial space has collapsed, and you have to high conviction in the potential rents to transact. 

Of course getting it professionally done is better...I changed the sewer lines myself... it was a total gut... kinda hated the work... and I definitely hate crawl spaces... not the best experience, but ended up good and inexpensive (money wise... at least)

The easiest way to get started is to look into generating extra income from your new house - rent out rooms, extra space, babysit dogs, provide storage, etc.

It seems over the past year we went from high cost of materials to build to high being a bit expensive to borrow money for projects especially if you are new in this space.

We then furnished all the shared spaces and prepared the bedrooms with curtains and a new egress window in one.
