I have seen it go up thousands of percents since I started accumulating.

Especially if you have never cleaned the ducts (and you would be surprised how many properties have not) you will be amazed by how much lint and dust can accumulate over time.

I was recently laid off and have accumulated about $20,000 in credit card debt, primarily from paying last year's property taxes and covering a few months of living expenses.

In the beginning you will spend more time learning how it works, but at the end if you are accumulating rentals, I wouldnt expect to spend more than 5 hrs a month.

What approach did you take to accumulate your properties so fast?

I simply budget 5% for capital expenses and 5% another 5% for maintenance and work with the money that accumulates in that pot.
