we get a LOT of leads from http://www.MHBay.com
I would say it is well worth your time to market your available homes on there - it is very inexpensive compared to the newspaper.
It is not a sexy looking site with all the flashing this and that - but the SEO is amazing, so when people are searching for a MH to buy or rent, MHBay will come up very high on the list.
I know I’m not going to convince many of you that a top website is worth your while, that is not my job. But for those of you who understand the quality website plan - get one, your bottom line will thank you.
