IMO the better bet is to stay in that 80k range.

The more of the following you are able to provide, the higher a price you can request:Inspection report by licensed inspector, legitimate sold comps within 0.1 mile range, roof warranty from licensed roofer, permits for the work performed, disclosure of how much electric/plumbing/HVAC was replaced, warranty for the heater (if new) or disclosure of what service was performed, age of windows and grade of windows (if new), warranty on appliances (if new), last service on appliances (if used), grade/brand/color/installation date of cosmetic materials (flooring, paint, etc.), etc.If tenant in place: strong lease terms, proof of payment history, screening criteria including personality screen, security deposit & last month rent held, annual lease term, etc.  

I know the market is hot there but I have not had any bidding wars.. most stuff I sell before completion but offers come in a little under list routinely and we counter to list or higher if they want concessions... ( this of course is new construction infil in the 450 to 650k range there in Charleston)

New and broader range of risks will emerge in future. 

Or at least a range.

I search for homes in the $60,000-$150,000 range but seem to mostly find condos/townhomes and apartments.If you were me & had $10,000 to start with, would you go the buy/hold route with rental units?

If you look at everything in the neighborhood in your property's square footage/age/condition range that's sold in the last 6-12 months in the neighborhood, as well as every active and pending listing in the neighborhood, you (or a local broker that's competent at analyzing that sort of data) should be able to get a really good idea of what needs to happen to sell your house.

From this data, you can utilize a website bestplaces.net that will give you a breakdown of the percentage of homes that sold, in various price ranges, for a given zip code.

Cost to list + changes to listing.Can range from $100-$400 for the exact same listing on the MLS.

There's more the 60 properties on the market right now that could fit your criteria and it'd be easier to narrow the search down with some more info like price range, area, desired rate of return, etc.
