I'm in a house in that range in one of the towns you mentioned.
First, hiring someone here is a lot more than in many other areas. So, someone from a midwest state is not likely to have accurate information on costs, for example.
A lot will depend on the particular house. Is it a small house in great repair or is it a larger house not in great repair (both might cost the same to buy).
A lot will depend on how handy you are. Can you do most repairs or will you have to hire someone for everything (or something in between)?
How picky are you? Do you need everything to look like it is ready for a Better Homes and Garden photoshoot or is a little rough around the edges ok?
What you count as maintenance? A bathroom redo might be maintenance or might be remodeling. Sometime something needs fixing and you decide while you are at it to remodel. How to do the accounting?
We did some major renovation (turned a small ranch into a large cape) back in 1996, put on a kitchen addition in 1999 and did a major kitchen remodel (though I did the kitchen remodel including milling the raised panel cherry doors in my shop, so that was very cheap), 2003 was a new patio and sidewalks, 2005 was a complete bath remodel to finish off the redo of the entire house, 2012 was new porches all around, one of which was really maintenance. The up shot is we spent a great deal of money turning a tiny, cheap (second cheapest house in town the year it was bought, cheapest was riddled with termites) into a nice home, if modest by the standards of the new $1M+ homes going up in town. We finally have a nice if modest home, and the total cost was less than if we bought it in this condition, if only because I did a lot of the work.
If you buy a house like this you will likely want a large repair/remodel budget. Otherwise not so much. I guess we have been through every appliance in the house, so that is maintenance, but was handled by cash flow.
So far we actually spend little on "maintenance" since most is "remodel". However, the roof is now 17 years old (looks great), heating is 17 years old, upstairs bath is 17 years old... They seem to be doing great, but at some point maintenance will be needed.
What we have done is along the lines suggested by Aptenodyte for what maintenance we have done or expect to do. The two major remodeling efforts (second story and kitchen addition) were done by loans and folded into ever lower rate mortgages. Fortunately our liquid funds (emergency funds) are more than large enough for any foreseeable maintenance. Back in 1993 when I bought the house I had a lot less money and had to save monthly. I did not keep separate funds (house, car, emergency). Of course I still save monthly. Habits you know...
We live a world with knowledge of the future markets has less than one significant figure. And people will still and always demand answers to three significant digits.
