How much would a greenhouse without any climate control other then built in vents extend my growing season?

Depends where you are located. Where I am 38 lat it allows me to start mid Feb. It doesn't get cold here until the end of Nov and little or no rain so it doesn't do much on that end for me but if you are in an area where you get rains in the fall then it will help reduce any mold problems.

Im in the lower 40's lat., basically Im wondering if I would be able to grow until the last week of Oct at least.

As long as your nights are frostless then yeah end of Oct is doeable. You can also place a couple of 5 gallon water bottles in a greenhouse to passively keep them warm the water heats up during the day from the sun and because water cools down slowly they will keep it warmer inside during the night.

Bets thing would be to get some form of heating gas or electric , water isn't such a good idea because it also makes the humidity of the air higher which isn't favorable in relation to budrot

Cant afford that though, not currently anyways, otherwise Id get a fully equipped commercial style greenhouse put up, but the one Id like is around I wanna think $10,000 or so.

You can't really use a heater in a portable GH they usually are too small and being plastic not the safest of things. I know in the UK that have these great heat tubes but we can't get them here in the states. With the water I forgot to mention that you use sealed containers so they don't raise the humidity. Also if you get frost forecasted (unlikely I know in TX) and bringing them inside somewhere isn't doeable then you can place a fan in there which also helps.
