@Quentin Moore - Sorry I was away for a few days and didn't check biggerpockets.
All my properties are 4BDRs, my biggest concern with 5bdrs/6bdrs becomes parking. The ideal vacation rental in Davenport should have 4+ bedrooms, a private pool and a low cost HOA for maximum returns. I'm not a fan of 3BDR due to high inventory, low nightly rate and not that much less expensive than a 4bdr.
My 4 bedroom homes accommodate 8-10 guests, my HOA is very strict on street parking and often times I have issues with Guests having 3 vehicles and parking one on the street, sidewalk and etc... I use the garages as game rooms so there are no alternatives for parking.
If I was to purchase a 5BDR home, I would set it up so it can accommodate 14 guests, 3 rooms with king/queen and 2 rooms with double bunk beds for up to 4 kids in each room, this will allow you to host up to 5 families pushing your nightly rate and maximizing your revenue. The biggest challenge is finding a property that has parking for 4-5 vehicles.
As far as price point goes, it all depends on the number of bedrooms you are looking for. I suggest doing the math backwards so you can take into account the HOA costs. The total cost for my properties after furniture appliances and etc.. is about 260,000 , my HOA fee is $180 and it includes internet, cable, and lawn service.
It costs about $480 per $100,000 financed, so if I was buying a property that Internet + HOA = $660 vs $180, in my eyes I need to buy that property for $160,000 to achieve the same cashflow as above. I know this can be a confusing answer but the point I'm trying to make is that in Florida no all properties are the same, HOA fees and other fees are very important when calculating your return.
