You can supplement these purchases with some of the taxed cash above. 

Mixed use can make more sense under deed restrictions if you're looking to supplement the cost so you have a free place to vacation to and use in which case you should love the property.

The money from the airbnb has been used just as supplemental income (helping family, paying on student loans, traveling etc.).

You could also supplement that education with some reading while you earn money in your sleep and on weekends without having done any of the actual work yourself.

If another 2008 is coming I’d rather have as many cash flowing rentals as possible so that I have supplemental income.

If I have this supplemental income I won't have to work anymore, barring no unforeseen rent decreases due to economic crashes. 

Being an agent you're more likely to have access to supplements that would give you the details on this as well- and you know it would be mentioned if these were two separate parcels for property tax purposes then (at least as far as seller knew). 

Very interesting take, I know in the area I’m in,its highly sought after for its own merits due to shopping centers, movie theater, brewery, grocery stores going up.. it’s a property that I see the neighborhood continuing to be a good one.. but the amount I can have in my pocket afterwards is super enticing and was thinking it can more than supplement my funds I’m already sitting in, just waiting for a deal to come up.. so yeah, I hadn’t put much thought into the taxation part of the sale, so thank you!!

My overall goal as of now is to have a good amount of passive income to supplement my salary, be comfortable while giving my wife the ability to go back to school or pursue new work if she wants.

@Joseph SchommerI love the idea of having a steady but seasonal job and the supplementing with rental income, to me, flexibility is everything, you could take on bigger projects in the off season and reap the benefits during the on season!
