I like WHYRENT. I wouldn't do #4 SLUMLRD!!
For me, I'd probably get HOUSKAT or HOUZKAT. Hmmmm

Kat Palmiotti thank you for the feedback. Slumlord was my Avatar name for many years on various online communities. It may not be the most professional sounding nickname, but it did create a number of first time home buyer and investor clients over the years since it started conversations about investing in real estate.
I was doing some research on possible names and had to laugh at this one:

I went with the WhyRent option for one of my business vehicles and this one for my new one since it ties in with my email address and my toll free number.

I think I will go buy some Googly Eyes to use as periods between GO.OWN.IT
I thought about everything like that but couldn’t bring myself to do it! Good stuff!

Previously, one of my cars had "IDNUHMZ" for Idaho New Homes. It was fun watching people trying to read it and guess what the heck it meant.
I bought my wife "MY3SONZ" when she got her cherry red Monte Carlo Pace Car so all the guys would know if they chased her and caught her, she came with excess baggage (grin). Actually it was a testimonial to our three sons who are now young men, so we might let someone else enjoy that tag next.
