A non-home depot supplier may get you a 30 year warranty quality window for only $300 if it is expected to be used a lot.

For the kitchen and bathroom remodel, if you have a bit of a discount from suppliers you can do a nice kitchen remodel for around $12,500, low end for around $6,500, bathroom remodel for around $4,000-$5,000. 

Young people can be into conservation and being "green" - something you can check out about them up front; if they have chosen an electric supplier that uses renewable sources (ask to see an electric bill when you get their application) they are into conservation.Since those bills come monthly, I don't foresee a huge water bill like what was just posted in another post.

Also our hvac system comes from a supplier.

We’re located in southern Ohio, so I’m hopeful your supplier recommendations are native to our area.Thanks again

Look around for a supplier Trying to unload mass amounts for cheap.

@Levi Trentham hey Levi, I’ve interviewed some excavators from the area and found one significantly lower priced with a good rep and have some good recommendations on Log Home material suppliers.

If you aren’t sure of how to price things out you can meet with some contractors and suppliers and create price lists and build your cost database.I always plan for a 5-10% contingency depending on the cost and scope. 

Everyone would just ask their supplier to break out every invoice into line items that don't exceed $2500. 

They are already in the market where you will be investing and know it well and have experience dealing with all the people you'll need, such as contractors, city govt, laborers, building and zoning, material suppliers, etc.
