@Brandon Ja - The standard answer here is to check with your CPA, but from my standpoint expenses that add longevity and functionality to an existing property (including adding square footage) would make that a capital expenditure that can be depreciated over time.

Rentals are about function more than form.

The property should be clean, functional, and safe.A well-maintained property attracts higher-quality renters that will pay more, stay longer, and take better care of the home.

I've found that using thia tool has significantly improved my communication with tenants and reduced the number of late rent payments.Finally, I appreciate the reporting functionality.

WikipediaSustained and significant population growth: Prices and rents are a function of supply and demand.

Something that easily integrates to the Accounting module so that $ amounts from repairs are easily and automatically reflected in the Accounting functionality / reports.

A great high functioning portfolio along with a decent W2 goes a very long way to achieving your goals. 

@Shaun Hunt believe what you really want to do is start a "Master LLC" that can function as a PMC.You would then sign management agreements between Master/PMC & property LLC's and have all income & expenses run through Master/PMC LLC, and only have to "settle up" annually with the property LLC(s).Check with a qualified tax professional.

We also do a walk through, set expectations for maintenance, filters, lawn, garbage and go over the function of GFCI's, shut off locations (water, power, gas).

Do these companies typically have 3rd party services/placement agency/some function in HR to provide relocation assistance to a new/relocating employee (within the US or international).
