Exciting time!! Good for you guys.
I was shocked a couple weeks ago when a building inspector friend of mine said up here new single wides were bringing $100k +/- ....
NYS Building Code changes in last 10-15 years now dictate concrete slabs, tie-downs, etc. which add another $15+/- to site work just for the mobile home. Doesn't include sewage system, well, etc.
Double wide is likely money better spent. Better resale value.
Are there possibilities for Modular houses in Arkansas? They are often built quite well, since they have to drive the sections over the road...often similar construction to an on-site stick-built house. We looked at them 30++ years ago.
Obviously, for sewage system and water connection, you'll need to have an idea how/where you want house site to sit on the lot(s).
Is the water connection just placement of a Curb Box on your property from the water main, or are Curb Boxes already there?
In the near-term, that center property line might come into play when you're figuring out your site plan. Don't know how things work in AR.
In NYS, parcels can only be merged at certain periods of time, and they're finally merged 1x per year, before a Taxable Status date (March 1st in NYS). Just a caution, and I want you to be aware in case it pops up...took us about 18 months. (I already had part of my sewage system on the other lot....no sewage permits in required my Town....
Best to perc exactly where you want system to go in. While I used to know NYS sewage system codes real well, varies greatly in other places.
Looking at your pictures, the lots are pretty flat, but a little elevated from the road?? If so, up here that's a good thing..... Perc tests might not a problem at all.
As far as equipment, I can't see anything other than a Compact Tracked Loader.....Forestry Mulcher, grapple, Rock Hound, etc., etc......
By the time he's 9, your grandson will be able to "dance" with it..
Again, good for you guys!!
