Hi Glenn, thanks for the welcome. My long-term plans for this property could include a full-time residence. For now, though, I would like to make something "liveable" year round but I would still actually "live" mostly at my current residence. I have priced out some home "kits" as well as "modular" homes; the prices weren't really too bad, a small "kit" 1 bedroom 24 x 24 for 15,000 ish (just lumber,roofing,siding) or a 3 bed, 2 bath "modular" ranch pretty much turnkey- site work etc. for a touch under 100,000. My deed restrictions prevent me from a "trailer" type home.
The main thing I want to do for now is avoid the tax man, if I'm not actually residing there all year. Taxes in NY will kill ya! I have installed a 200 amp electric service this spring, underground 400 ft from pole, going into my existing building. I am contemplating a septic system sized for a 3 bedroom home so hopefully I can tie in to it if/when I am ready for full time residence. I still have to check more on this, but I think I can put in a legal septic without raising taxes. I was going to tell them I want to use it for my camper until I eventually build a home, if they ask.
