I would suggest retaining a portion of your cash for an emergency fund, a quick-acquisition fund, or whatever you would call it.

I believe it's circumstantial and the critical factor is whether the builder uses an affiliated service brokerage or retains outside brokerages to handle their sales.

A 1st time lead is expected to put up 25% min. of the total capital raise, and to take no more than 5% override or retained ownership.

Next time I would retain creative control to ensure that we are using the property to it's highest and best use.

@Kevin Lefeuvre - The only discount we offer is if they book 7 nights or more, or if they are a repeat guest as we want to incentivize longer stays and retain existing good guests.When we do get requests for discounts outside of the above we do not entertain them. 

Common fees will include a set-up fee, leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more.

It helps to retain your other tenants and keep the neighbors happy.

These three pieces of advice are all designed to retain tenants as long as possible.A little more on each...Most of my tenants are on their 4th or 5th year with me.

Also property manager/Broker combos that have one client interested in selling their property and since they want to retain the management, they deal it out to their investor pool off market first to see if another one of their current investors is interested.
