I do worry about the strain this will put on our already challenged infrastructure from transportation to schooling but I’m confident that we can work through it.

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.

This remedy comes in the form of a public transport system called "The Rail". 

…with good public transportation and closish to an airport.

There is no public transportation, but it is close to shopping, close to the interstate, and just a short drive from Atlanta.

I have owned a transportation company for the past 8 years and About two years ago I thought it would be a wise idea to take a pay cut and make investments into real estate.

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 have an enclosed trailer.

Transportation jobs are growing in Augusta and Savannah
