Idéalement un multi-familial, 2-3-4 plex

As for my next step, ideally, I'd like to expand on this current property.

Now of course it's ideal to get rid of a blighted home in a community, but you at the came time, create one less home for someone to live in if it were fixed up.

We're big on doing anything to make home ownership less of a liability and more of an investment, and it seems like owner-occupied small multifamily will be an ideal way to get our feet wet in REI without too much risk.

(Ideally you would want to put these on the tenant, unless your market includes them)Best general advice on assessments of your rents:Craigslist.
