@J PetersonI would think if you are having trouble finding multifamily properties in your area, you might experience an even tougher time finding a suitable vacant lot to build one on.There is also a time factor.

The other 2 seems suitable for a quick calculation.

Sell off license (which is transferable) for $500,000+ and rent property to new tenantsI am stuck on finding a suitable financing option for the initial acquisition of the property.

Discounts can be applied to improve the yield but usually the discount is applied for a reason such as a defect in the loan but certainly those reasons can be to obtain a suitable yield to make the investment attractive.  

one last thing, I would of built 4-plexes there in BCS but never found a site with a suitable priced to do it so we the supply is not getting larger with 4 plexes, its just resort apartments renting my the room

If you learn to provide value to a developer in some way by providing your time, cash, locating good projects, vetting deals for suitability, etc. you can learn that way. 

I'm not sure if a UPS Mailbox would be suitable - the lawyer said it would not be.

In short, Property A is larger and has a higher repair cost due to the high-quality materials than Property B, and in my opinion, Property A is not suitable to be a rental if you want to reduce the upkeep cost and turn around time for a new tenant.Both properties are located in good locations (close to schools) and I have rented out Property A before but due to property damage from the tenants, and the high cost of materials and custom features of the home, we decided not to re-rent this property and make it our primary resident.

If the shower and ADU don't have permits, the thinking should be it was not confirmed the unit is suitable for habitation.

It's just as likely that people will bargain shop based on the all-in price when a different rental would have been more suitable for a few dollars more a night.
