I just upgraded to the PRO Basic, and am a happy camper :) Best of luck!!

Tenant who has been in the unit for about 2 months contacted me the other day about the in unit stacked dryer being broken.

I don't have enough space to upgrade to ios7 yet..

I may sound like a broken record here but: search Bigger Pockets forums and podcasts.

As always, you have to buy right, at deep discounts, and don't expect to get the full bang for your buck if you upgrade very much.

In many parts of the country (I'm not familiar with yours specifically), to install/upgrade service, install a new panel and install/wire all new breakers, you're probably looking at a $1000-2000 if you're using an electrician who is accustomed to working with investors.

I would also upgrade the electrical panel for sure.

I wanted to upgrade the appliances to Stainless Steel however I didn't want to spend a lot of money and purchase new ones.

One of my units was broken into.

I have seen the epitome of that statement in Germany, where homes can be over 400 years old with proper maintenance and upgrades for such things as running water and electricity, LOL.
