Extend and pretend" won't work as well as the last crisis, because interest rates are rising, not falling as they were in the aftermath of the Great Financial Crisis.

@Julie McCoy, I don't pretend to be a seller-financing expert, but my instinct is that seller financing generally works best in cooler markets or in downturns when you really need to expand the buyer pool.

Pretend you're looking to rent a place in that area.

Pretend that each part of the transaction has to stand on its own, just as if you did two (or more) closings.

You can also "tour" the neighboring properties the old-fashioned way - pretending you want to rent and then chatting up the property manager.

Some yahoos like one of the dozen or so Yardi iterations, but I don't get those folks so I'll pretend it doesn't exist.There is a whole different class of PMSs like RentReady, TenantCloud, Hemlane, etc that CAN be used to do some or all the things you'd prefer, they just won't function AS well for as long as the pro-grade PMSs listed above.So, if this is a side hustle that you'll dabble in for a while and then hop onto the next shiny object that walks by, I'd go with the cheapest or best UX/UI you can find in the second group.IF this is a business that you intend to keep getting better at and pursue with excellence then I'd cut right to the pro-grade PMS and learn to use it masterfully.

Once you have a pretty good idea of what the market is like for the competition, then run a test ad with a "pretend" home to sell and find out how many calls you will be getting once you buy the park, and what kind of buyers will be calling. 

Also, when possible, you are trying to only work with buyers who are real, and who are direct (not a third party/wholesaler who is pretending to be a buyer), etc.

You can NOT deduct anything from a fake pretend business.

In the real world, some CPAs will continue their attempts to hack cost segregation, and most cost seg companies will continue to pretend to produce a "complete" depreciation schedule.
