@David Dachtera I just want to chime in for one more point, as you mention the complexities of multiple veils.

Competition - While we are seeing new apartment complexes being built, those tend to be high rental fees and does not compete with affordable single family rental.  

It depends how complex of analysis you want to do. 

I don't know if there's a gantt chart that will auto populate it but usually gantts are too complex to be general, they will also be inaccurate if you run multiple projects as your resources will be shared, there are also gantt chart online softwares for this, or a google drive with excel will usually suffice up to 100 employees working on 10 projects.

Since it is a complex transaction you probably want to study it pretty thoroughly.

I have a multimember LLC taxed as a partnership.For one trip using my personal vehicle for the purpose of renovating one unit at an apartment complex, total mileage = 100 x 53.5 cents/mile = $53.5Does the LLC then reimburse me for that amount, so that the expense now becomes the LLC's, and not my own?

Duplexes in this area can be associated with Class-C or lower areas as there are a plethora of SFH available in the area at decent price points or prospective tenants will choose from the many nice apartment complexes that have been built in the area since I’ve been here. 

You don't want to create problems for yourself by creating extra complexity with only negligible additional benefit.

At the apartment complex where I worked we often saw this in the homes during our turnover period (we always just repainted the entire unit).

I worked at a student housing complex for two years and we made it a requirement for students to apply with a cosigner/guarantor.
