Re: Looking to make my first boat purchase!
welcome to boating!
You have a tight fit on your requirements--you want something big enough for 6 active people, but under $5000; also it's better to start with a smaller boat--easier to handle and learn on. Being new, and this a family boat, the only boat, you need reliability and that costs money, too.
Anything that fits the above requirements will sell in a day, so you have to be prepared to grab it and, unfortunately, take some risks on condition. not nearly as risky with an outboard.
I suggest trying to stay on a single axle trailer if you can. cheaper, easier, less to go wrong. And an outboard.
Look for an interior design that maximizes open space. The popular (on lakes) bowrider inboard sofa boat is the WORST design in this regard. Since you are on a lake, you can go with a bay boat hull. Interior, look at center console with bow seating. All the children will ride up there. Wife rides next to you. No one sits in the back anyway. And of course, get that motor out of the way--you want an outboard.
Go to Sea Hunt as an example and look at all the families having fun in those designs.
I can't speak to deck boats but they also may be what you want. With an outboard.
the way to shop is to start with finding your design. window shop new boats at boat shows, on line and at dealers. only AFTER you have your hull and interior, start looking for used ones. otherwise you tend to find a boat and try to make your fit in it; go the other way and get a boat that fits you. With an outboard.
if there is one piece of advice for used boat shopping it's this: no title, no discussion. next, I'd recommend against any boat that requires any work other than clean-up, for a new boater.
We're not there yet, but if you are a new boater, never, ever, take the family on the maiden voyage.
