... I need to figure what it will cost me before offering him anything. I dont own the boat but I am looking to buy it, It needs some minor work to it the engine runs and shifts like a champ and the interior is in excellent shape. Im just figureing new sails, roller jib, mast removal so I can clean it up and repaint it and put new pulleys on it so I know it is good. ...
What you just rattled off sounds to me like a minimum $5-10,000 in cost, and I expect that you don't know the half of it yet.
I suggest you put together a spreadsheet of what it will cost you to put this boat into good order. Don't assume anything cost-wise, get real quotes on equipment...when you're done, put the list back up here and you'll get plenty of feedback on it. Unless you really just want to wing it.
The Ranger 28 was not a bad racer, but seems like a poor choice for a live-aboard or a cruiser...let me guess, is it available for a song, too cheap to pass up?
You will save yourself a lot of time and money, if you put together $10-15,000 and find a nice Catalina 30 ready for you to move aboard. If you feel you can't afford that, you don't want to get into a fixer-up. You'll spend even more, and likely end up with less.
Been there and done that...
