syndication company I worked for in the 80s that went under in 92.. the owner owned a premier apartment complex in Millbrae CA  ( just south of SF..

We have a single family home, a small commercial retail building, and now we are pursuing a 5 unit apartment complex.

On the day I moved in, I found out the property managers had other units in the apartment complex listed on Airbnb because an Airbnb guest tried breaking into the wrong unit (the police were called).

Building a Phase 1-5 messaging campaign is the easy part.I'd recommend you build this yourself, so you can see what's working and what's not, and improve it over time with added features, automations, and complexity.

Quote from @Jaycee Greene: Quote from @Zach Matson: I'm doing some diligence on a property that has an existing duplex, but I can build a small apartment complex on the same lot.

However, if you feel you don’t need a tax plan that complex, there are tax planners who specialize in working with real estate investors and can help you craft a tailored plan that’s more affordable.

On the other hand, they will manage investor's unit as part of an 'apartment complex' (https://www.zillow.com/b/6734-summer-fest-drive-109-110-san-...).

Essentially that's what you described doing, but with the added complexity of the auction process.

This can range from a few thousand to several hundred thousand dollars, depending on the complexity and size of the project

The rules are complex, and unequivocal.
