To be safe, I take driving license and verification ahead of showing time to ensure potential tenants are legit. - pros: Cheapest. one-time investment into tech- cons:  unsafe if potential tenants turn out to be a pain2.

Have you pulled a O&E report on the property and looked at that info for verification?

Typically only a few points higher than conventional but quicker to process + you wouldn't have to deal with hassle of moving, owner occupancy issues + MIP with FHA, PMI with conventional, and most importantly all of the income verification / underwriting for both of those.It all depends on what's important to you (rates, cash to close, speed to close, moving, etc) and what you can qualify for + working with a lender to comb through the options.

I would verify their identity at a minimum - like you said getting copies of their licenses. 

Solar makes living in a home cheaper, a pool has the opposite affect so it's not apples to apples.The math is simple with solar, if there are 2 identical homes sitting next to each other and one has a solar system like I have (8kw) that cost me 19.5k after tax credits, my house is worth 19.5k more, minimum.  

Pretty much identical to my story 5 years ago when i got into it at 19.

In fact, there was a nearly identical post 2 days ago...https://www.biggerpockets.com/...

We have found that using Airbnb and VRBO's maximum verification works best for us.

The mechanics of a personal vs business savings account will be nearly identical meaning they work the same and the interest will be roughly the same. 

In March of 2022, an identical house like mines sold for $875k in same sub division.
