@Andy SabischNot the 1031 exchange route... usually if the property is sold a year from when acquired, seller is not classified a 'dealer' for income tax purposes.

@Dawn Brenengen @Graham StoreyWould you classify Bradbury as an undervalued neighborhood?

They tax side hustles as though you were professional but do not allow the advantage of being classified a professional when it should be able to be to your advantage (note I am not against setting qualification to be a RE professional; I am against one of those rules stipulating that it has to be your work hours greater than other jobs). 

If the two veterans are not spouses, this is classified as a joint loan and likely will be required to be submitted to the VA for prior approval. 

What I've found out from the county is that a property(which mine is)must be classified within an open USE zoning district and their definition of a short term rental is posted below.The ordinance defines a short term rental as follows: Vacation rental means no more than two single family homes with a combined total of no more than 9,000 square feet gross floor area which are rented for two (2) days or more to tourists, vacationers, or similar transients.

It took effort to find the property, purchase it, rehab primary, and get additional unit classified as ADU.  

Also, this is NOT classified as a sale. 

In general the activity engaged in at a property is what legally determines how it is classified.

Doors per person depends greatly on the ability of the person and the type of door (apartment that has clustered doors vs SFR's all over town.I don't think you can classify income potential on a per door basis as it will again greatly vary depending on the door.It is a 24/7 type of business, even in the middle of the night.Good luck!!!!
