So, why not just borrow as much of a percentage as they will allow from the outset?...

Since I don't know the area in Orlando very well, I have a job that allows me to call anywhere home and the Orlando area is a place that I'd like to invest in due to its proximity to parks and a potential job offer for my significant other.

However, as @Andres Verney suggested, if you get a percentage off of other people's rentals, and roll that into your own, that could help you on your way and allow you to minimize the expenses on your own rentals.

However, we're finally at the point where we'd like to start making offers.At the moment, I first calculate using the typical BP rules-- 50% rule, 2% rule (I allow them to go down towards 1.25%), 70% rule with flipping estimates, $100/month/door, etc...  

Or has the change in occupancy allowed me to back out if I desire?

But two years later, I moved but the bank allowed me to keep it. 

I'm not sure why no one has mentioned this, but under ORS 90, children under the age of 2 ARE NOT allowed to be counted when you are establishing your policy for maximum occupants.You probably know you are permitted (not required) to limit occupancy to no more than two people per bedroom.

I have noticed a number of for sale signs but don't know if zoning allows nightly rentals.St.

I have been through 4 banks, 2 credit unions, and 2 mortgage brokers now and none of them will allow the seller to carry. 

Daniel Karbownik you are right about the lender most likely not allowing a financed down payment.
