You tend to see higher turnover when it's that small; good chance the property owner or property manager can't find people that a) only want 700 sq ft and b) are willing to sign a 5 year lease. 

On the other hand, single-family (typically) provides a tenant pool that can be more manageable and longer leases, and I am assuming maintenance and capex could be on a smaller scale, but I could be wrong on that. 

Any forwarding order for these tenants may be over so you probably won't get in contact if you try to mail them but you can check if the utility company has recently sent a paper bill although opening other peoples mail is illegal of course.

Yes, this can be done and people do it all the time, especially now.

@Minh Vuif you have to ask random people on the Internet... pass

My main goal is cash flow right now since I have recently retired and the money coming in each month is important to me.I would love to connect with other investors in the area and get some advice from people who have had success in Charleston. 

GerberI usually recommend people read the E-Myth an then read Traction.

need massive power close to said land.. also keep in mind they employ very few people so its not a long term thing for employment

I know people who have deals on the market right now, none of them WANT their deals on the market right now.

After paying closing costs, title fees, appraisal, origination, underwriting, processing, legal and other fees, the typical refinance costs about 1.75 - 2.5% of the loan amount just in closing costs (obviously before people yell at me, this varies drastically by state, but having done loans all over the country I find this to be a pretty accurate estimate).  2) Keeping the average 2% cost in mind and the fact that people typically refinance when rates drop about .75% - 1% or more, I wanted to see if paying an extra point now when I was already paying all the closing costs to buy the rate down made sense. 1 point can get you between .5% - .625% off the rate depending on the days pricing and the coupon you are pricing.
