Another thing to note is there is no mention of using the garage in their lease (I inherited these tenants and they had already been using the garage with the previous owner, and when they renewed with me, my lease didn't state anything about using a garage).What I can do (but don't want to do) is to delay my project AGAIN by having my construction guys come by a week later after the shed is built, to give the tenants time to move their stuff (will the shed fit all of their stuff?

Unless you have some nefarious plan of defaulting, which still doesn't necessarily prevent someone from abrogating their losses against you later. 

Then, years later when we sell, is it a problem that the names and ownership is split, or could a single 1031 exchange be done, treating us as one entity?

We refinanced out two years later, dropping PMI after adding $130K in equity with construction and the "Covid bump," dropping our payment from $2200 to $1680.

We walked the property and 2hrs later made an offer, in person. 

Once the contractor finishes you then bring the inspector back for another test, and $300-$600 later you should have a lead certificates.

This is what I am doing first unless some amazing deals just come by sooner rather than later that are impossible not to take advantage of. 

However, I am contemplating purchasing a condo until I could increase my savings to try again later. 

In terms of scaling money now is usually better than money later...In my opinion, knock out the closing cost.

Yes, the Oracle building changed the market some (as did the Gigafactory), but the HQ change came later and didn't seem to have a noticeable impact on the overall market.
