I am happy with a 400-500 month CFlow at the loss of cap growth if I can BRRR my way into the CFlow

The bad is that often times you will find less care is being taken with your property, the Section 8 has inspections, which at times can be obnoxious and often times you are renting to tenants with no job or limited employment, so they are home all the time, causing more wear on your house. 

I bought last year my first commercial building, a 12 unit, and it has been very difficult since inception.First year I had a management company that wasted a lot of money and caused me some large losses.

I request a credit limit increase twice a year on my main card.  

I believe there are limits for the credit, but it sounds good in theory though.

If you would like higher limits than $1M, you would get an Umbrella Policy.  

A first-time investor with limit resources to fund the remaining balance of the loan.

The main thing with real estate investment, from my limited perspective, would be to find the niche that best suits your investment style and personality and learn everything about that niche and do it as well as possible while continuing to learn and grow both your business and career.
