It gives you the flexibility kind of like a credit card that allows you to borrow a certain limit and withdraw funds as needed.

@Kelly Taylor who doesn’t like tax free atm withdrawals?  

Just make sure you are saving towards those slow months during the peak months, buy a deal at the right price (don't overpay just because its a turnkey STR or you think it will make more money than projected), and look into ways to increase bookings during those slow months with some marketing and operation tweaks. 

Eventually I realize that when I think about living on post-expense rental income, I’m treating the income as the “withdrawal rate”, in Boglehead parlance.

Then connect with some hard money lenders (you can find some here on BP as well as some who are typing this right now) and connect with them to understand their product type, what they like to lend on and requirements.Hard money broker is all numbers game of making relationships and helping those that are looking for financing, it starts out slow but if you get with a few good borrowers and lenders it can be pretty decent money to be made.As an example we paid six figures last year to HM brokers. 

Also, to track spending habits - just had a prospect withdraw their application when we asked why they were spending half their income on gambling websites.

Agree with @Caleb Brown - go slow and do 1 thing at a time.

However going into the summer my bookings have slowed down, i do not currently have a pool. 

Rented quickly for prime in rent in slow season.

Would have done better if not slowed down by COVID in 2020 Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?
