For example, ceiling fans in the master bedroom and family room, improving the curb appeal and the front entrance area, fresh paint, etc. 

I am going to add a fenced-in deck outside in front of the entrance too to complete the whole project.

A year later I moved and rented it out and moved in with my fiancé and her parents and built a separate entrance to their house for privacy.

We have a problem with tenant loitering in the back of our building which exits to the parking lot and is a frequently used entrance/exit for most tenants.

That would buy a lot of entrances to conferences , networking events etc

The basement had two entrances.  

The lease she took over say rent as it is.I personally would hate if someone email me such a long list of small things .After, moving in physically wenoticed a few broken issues existing in the apartment andthey are as follows:1) The kitchen has a cracked threshold in the entrance on twoplaces and it is moving.2) Some of the cabinet doors in the kitchen arebroken.3) The first closet door from the entrance is off its hingesand has to be closed forcibly.

Hook up with a few investor friendly REA's, and let them supply you.The bottom line of how comes from your answers to three questions you should ask yourself before you go any further:1 - What are your financial goals...as in your financial needs monthly and for total payoff of your personal debt.2 - What Market (Micro-Market actually) will deliver properties with financial profiles that will satisfy the needs from Q#1.3 - What Entrance/Exit Strategies (this refers to money...not "flip", "hold", "land contract", etc...) can/will you use to deliver the above 2 Questions.Only you can answer the above three questions, because they are specific to you....and a hint:  None of the answers involve a "%".

Now I'm on an entrance street into the same subdivision, the "upper-class" section of it.

Things that come to mind are bars around windows and a heavy metal security door over entrances.
