I'm going to start mixing it up to see.

As far as insurance, the only time it was an issue (and didn't create one as the dog was very well trained when we actually met him, so we didn't push it) was when my property manager signed a 2-year lease with a couple that owned a rottweiler as they put mixed breed on the application and the manager never met the dog.  

My background is a mix of finance / legal / entrepreneurship, which I'm hoping proves useful as I start building out a real estate portfolio.  

At this point, mine are a mix of MLS, partners, fsbo/word of mouth, and wholesalers in that order.  

However, trying to find similar sales of a 24-unit apartment building with a jumbled mix of one-bedroom and two-bedroom units in a low-income area proves to be too difficult.

Personally I don't like to mix business with pleasure.

If you don't have huge $$$ to spend on advertising, get out there and MIX IT UP.  

I think you may be mixing up taxable income (what's on schedule E) and cash flow (the net money in your pocket.) 

Our clients are a mix of investors and homeowners who have decided to lease their homes rather than sell.I do invest as well, both single family and a bit of commercial.

The risk involved in having that breed (and other variations or mixes) is not worth the reward.
