I'm an investor with a couple properties as well as a CPA. 

.- Payments to investors are automated, so rental income is distributed directly without much hassle.What I found interesting is that this solves a couple of common issues:- Property owners can raise cash (for renovations as an example, or any other need) without giving up control of their property.- Investors get access to real estate cash flow with lower costs and no landlord responsibilities.- The whole process is simplified—no co-ownership legal headaches.I’m curious about the pros and cons of something like this.

If they can build a larger home and sell it for the same or more rather then building a couple small homes why do it?

So get a couple of hundred there (after HOA & note). 

I’m a 22 year old firefighter that’s looking to own a couple of rental properties.

That means their pricing tool is designed to price beneath the rest of the market, which drags the entire market down, especially when combined with their algorithm changes a couple years ago that made pricing (IE lower prices) the #1 factor in ranking.Even if you use an external pricing tool, it gets dragged down by the people using Airbnb's pricing. 

HI,I was curious to hear from other professionals, when you have a tenant for a couple of years, and then he wants to add a new person to the lease, what steps would you take?

Over the past couple of years, I’ve learned a lot about the business—like how to analyze markets, underwrite deals, and connect with brokers.

@Tod DuBois couple of thoughts:1) If you're getting that many leads - raise your price!

Usually all you need is a couple really good comps to know how your property would do and that is easier to find with a paid version of Airdna.
