I personally would avoid the older neighborhoods closer to the post.

You'll most likely find your staffing costs to be in the neighborhood of $1,200 to $1,900 per unit per year, depending on property size, class, and market. 

My client is interested in investing in a new-construction build of a 23-unit apt. complex in a great neighborhood in San Diego. 

They will also be using it for a STR/college style rental property as well.

Some of my clients love the cash flow in the east side neighborhoods over by Slavic Village and Broadway selling between 90-110k with rents up to $1,800+, but just really depends on the types of neighborhoods you're investing in and your risk / reward threshold. 

A larger storage building (10X 12 tall barn style) is in the easement and I was told they would move it and move it back, at their cost.The access to the two rear units will be obstructed and damaged by the heavy equipment and the tenants will be upset and don't have another place to park their 4 cars.

Construction style matters. 

You can sidestep most of the headaches if you stick to these five golden rules:- Know Your Market Inside OutTake time to research neighborhoods, property values, and what buyers are looking for.

It’s also important to really get to know the neighborhoods you’re considering.
