its a 6plex currently and plan to make it to it's legal configuration of 5plex (here is one of the upgrades, still a work in progress)

Summer has higher demand for rentals, meaning you can get more than you would this time of year.I just bought a duplex in Ferndale actually, an upper/lower configuration.

For those who are self-employed with no full time employees, the Solo 401(k) format provides similar checkbook control over funds in a slightly different configuration - but with a more robust retirement plan.Several providers of both services are active here on BP.
