Combined they allow the state to completely override the city of San Diego's ability to set density limits or height limits within 1/4 mile of public transport.

I am wondering if anyone has bought property in the area or knows anything about the town as far as schools, transportation, crime, taxes, etc.

There isn't good public transport outside the loop.

If you have no money saved up, you should ride the bus.If you have no money saved up, and you can't bring yourself to utilize public transportation, you should buy (not lease) the cheapest used car you can find. 

I have an enclosed trailer.

first property 948 Sq foot 2 bed 1 bath enclosed back porch.

A recent look at investments in the transportation industry suggests a possible opportunity in truck/trailer parking lots.  

STR might also see an uptick for "staycation" type travel in the coming months or years with people wanting a time away in a space other than their home, yet also wanting to avoid the use of public transportation including airplanes.What do you think?  

Pricing depends on many factors and some properties just aren't a good fit for many reasons - the main ones usually being location, access to public transportation, and size.

I would look to your building codes for new units as to the parking requirement, with the ADA, larger complexes will be effected as to the parking count per unit. 1-4 single family may not be covered but that should give you an idea of the statistical requirement based on concentrations.I would want at least 1 1/2 spaces per unit with a 1-4, meaning 6 spaces with a 4plex.If this is "downtown" your market may be different too, many urbanites walk, take public transportation or bike and won't own a vehicle, look to the make-up of the tenant base.Look to comparable units and what parking might be.As to valuation, parking space adjustments will be objective, guess, I would use the cost approach of adding additional parking.
