Best south Florida real estate loc. to buy house with dock.

Well, the able to dock a 100-110' yacht at the house is going to be the biggest consideration. That limits the amount of deepwater houses that are even suitable to probably 1/10 of 1% of them. Focus on the dockage needs and find a suitable house.

Cheapest house/most bang for your buck to accomplish your dockage needs would be probably Pompano Beach/ Deerfield Beach or up the New River,even Lighthouse Point but draft is the other big consideration, how much draft do you need?

The other consideration is the crew. You're going to need full time crew on that size, a minimum of 2. Might be best to buy a small house with lots of dockage, and let the crew live in the house. You cannot live on board in South Florida behind a house.

The weekly vacation rental house thing actually works out pretty well down here. But again, can't be working on a yacht in the backyard while guests are paying good money to stay in the house.

For all the reasons Capt J points out, there is a world of difference to solutions between the 69' and a 100-110' and as boats tend to stretch, even more to a 120'.

Staying within South Florida, you can find many homes that will fit the needs of the 69' for under $1 million and do ok renting them out as vacation homes. You do need to be careful they meet legal requirements for transient housing which sometimes requires modifications to older homes as those requirements have stiffened considerably. In the Pompano area you can find quite a few houses with 70-80' dockage.

The minute you start talking over 100', you push the price of the property up considerably. In some neighborhoods, just the lot is going for $3 million plus. Moving north of West Palm you find larger lots for less. However, you're then still back to the issues Capt J mentions plus one more. The house as a rental property investment is more problematic. Fort Lauderdale and Miami are the best vacation rental areas. To vacation renters though that extra lot width isn't something that matters to them. So you're talking more expensive property without being able to push the rental price up.

As expensive as dockage is, make it 100'+ and add crew and I don't see how the marina doesn't still remain the most economic route. There is a wide range of dock prices. For instance, Dania Beach is significantly less expensive than Fort Lauderdale. Move north of West Palm and prices start to drop. His idea of using the house for the crew is reasonable but not likely to come out better financially than renting dockage. Suddenly you've got a million dollar house for your crew with the associated costs. He mentioned draft. Most homes are on canals and depth may be only maintained to 5'. You will find homes with up to 9' depth but no commitment or obligation on the part of the city to maintain at that depth so can lead to dredging costs for you. A house fronting on the ICW solves that issue but then isn't the best place to keep a boat full time due to traffic and the cost of a 120' lot on the ICW is even higher.

You can dock the boat right here while looking for a house with a dock:

Yeah, I think the apartments are rentals only, unless that changed in the last few years.
We go there all the time with the boat, sometimes with charter guests to eat and drink at the restaurant.
Food is good, but not great.
About 4 years or so ago they changed a chef or manger or something, it was good quality, almost gourmet food before. Now it is okay, not great.
Lots of rowdy yard workers coming there for drinks after hours, smoking is allowed outdoors.
(I am a redneck and fit right in, but had to quit smoking before it killed me)

So, uh side tracked again.
This was about dockage for a 100' boat.
Running up and down the New River frequently I see signs for docks available
In that size range.
I can look next time and post a picture of such a sign, but it will be a while, going abroad for the holidays and put the boat to bed last night.
I run and manage quite a few smaller docks in my neighborhood, but not in the size range.
I have a an opening for a 50' boat on the river right now, and a 55' on a canal the next month or 2. After present boat sells)
Also smaller boats, 40' and under, plenty of docks.

OP: Have your Captain run around on the canals and rivers looking for "Dock for Rent" signs, they usually specify max length. Lots of dockage available in Fort Lauderdale, but kind of a Grey Market as a City ordnance prohibits renting docks in residential neighborhoods, and especially prohibits any liveaboards unless apporoved pump-out stations are installed.
Also look in the waterfront news classifieds.

It depends on zone so not as grey as it could be. Only zoning of RS-8 and RS-4.4 can not rent docks.

This is the beauty of the internet and bulletin boards, always somebody who knows more than you and they are not shy about putting it out there
Sorry if I was wrong, but in all my 18 years in this town, on the waterfront, you can't legally rent a residential dock.

Probably can't where you live. There is nothing especially logical about it. Pretty much any property that is zoned to allow duplexes or condos, even if it is a single family house. You can rent docks on Isle of Venice, but on the other side of the same canal on Fiesta Way you cannot. You can look up any location on the maps of the Broward Country Appraiser.

Regardless, when you get in the 100' range, there's not a lot available. I found one on docksearch. 100', 6' draft, $3,500/month. On dockandslip, a 100' with 8' depth in Pompano for $2000/month, in FLL 130', 8' draft for $2200 per month.

Of course the OP's question was where to buy a house where he can keep his boat.

Yes you can in some area's. In Lauderdale by the Sea, they want you to get a $7 annual permit to rent your dock. Most neighborhoods in Fort Lauderdale it's legal as well.

AND, some chilly winters But Jacksonville is a beautiful area. I love that neighborhood built over the marsh that goes from the ICW to A1A.

Yes, and Hendricks Isle and 2 more in the same 'hood.
Those canals are not residential however: They have car parking, pump-out stations and toilet/showers on the hard, all included. Like mini-marinas.
I have docked quite a few boats there over the years, great area, but the dock rent is twice as much as in the residential canals I am talking about.
The "Residential Canals" in my neighborhood and up the New River is strictly private docks, behind private houses, and that is where a majority of boats keep renting docks for about $12 per foot per month.

I was just using those as examples.

Cool, but them canals are the exceptions rather than the rule..
