I'll definitely check out that article.About your comment on the 4-plexes, is that nation-wide? 

@Casey Charkowick I think you need to do some more research to narrow down your expected rents a bit more - the range $2400 to $3000 is pretty wide, and makes a big difference.By my estimation, it's about a 2% cash on cash return if the rents are $2400/mo, and about 5.5% if they're $3000/mo, with debt service coverage ratios of about 1.18 (bad) and 1.48 (very good), respectively.If the realistic expected rent is $2400 I would not do this deal.

Property class varies widely by market and C class in one market can be a lot different than in another. 

Yard sales, especially community-wide ones, are an opportunity for much-needed social interaction.

An overwhelming array of variables influence our financial markets.

Examples would be brick wall views that aren’t visible in photos, really wide angle photos that make rooms appear much larger, etc.

A ranch in Arkansas with 500 acres and a triple wide sitting in the middle of it will be taxed (assessed) much differently than a 800 square foot bungalow on 4,000 square foot lot, overlooking the Malibu bluffs of the California coast.

I also like the wide and varied perspectives from different investors.

I see the advantage being in a wide array of different people available to complete the job, different bids, investor friendly contractors, etc!

Seems to be fairly straightforward and allows for both debt and equity stakes, with wide strategies (private/public commercial, fix and flips, residential, etc).
