One can have dedicated ground even with EMT conduits for certain devices, and many older circuits can have MWBC where neutral conductors are shared on opposite leg circuits, so it's impossible to pass or fail an inspection with unoccupied conduits and boxes only.The OP seems to be doing the job of the GC is she is actually dealing with the logistics of the different trades. 

Depending on the purchase price (or cost to build) a feasibility study might be a good confirmation of what you think you know about the property and market but it is never a replacement for doing the leg work yourself first (until you get to the point where time is tighter than money! 

If he has been living in the house for 20+ years and is a moderate to heavy smoker, there may be rooms where scrubbing, sealing and painting simply won't keep the chemicals from coming to the surface and you will end-up pulling down the drywall and hanging new.We renovated a house some years ago where the former owner had a favourite chair in one corner of the living room where she sat and smoked.  

Costar always wants my first born and usually my arm and sometimes my leg anytime I ask about their products but I will check with them.It seems only some counties track ground lease properties and most don't have an easy way to search the data.

Without paying an arm and a leg in interest ratesWhat key aspect of this “niche” do I need to focus on to insure positive cash flow?

So naughty me for being a negative sod on realtors (heck I was even one myself for a brief time 22 years ago in Australia, but got fired when I broke my leg on a 'vigorous' house inspection!). 

That would mean my tenants would have to buy and pay for it and do all the leg work in the event of a line break, like we are currently experiencing.  

Whatever you choose, very best of luck on the next leg of your REI adventure! 

I would hustle and save for your first cash flowing deal outside of the retirement, and even partnering is a great option too to get that capital for the first deal and you do all the leg work.

Best of both worlds after I weighted out the options. 2100 a year for a 200k property is a great deal for an investor I will have to look at this more.. if that's what the tax rate is there.. then Charleston should move to the top of out of state buy and holders list.. that city has legs..
