Ideally something that is on web/app that'll allow me to keep track of different items come tax time. 

Mortgage rates are driven by the capital market and basically follow the bond market, specifically 10 year US treasury with a premium, historically about 1,7%.Yesterday the 10yT fell to 3.9% and I have seen 5.99% 30y fixed rates with a local bank in here Milwaukee (that is still an inflated 2% premium), so 5.7% would be historically normal based on a 1.7% premium, even without the 10YT going any lower.Here is why.If the 10yT offers lower returns, more investors want to buy mortgage-backed securities instead to get higher returns (about 1.7% higher), as a consequence lowering the returns on those as well.

Still better than renting and wasting 4-5k per month on a place that isn't even as nice or big as the home I was able to secure.

I have looked through the Offering Circular and it states (contradictory to what they state on the website) that the notes "are not secured by any collateral and are not guaranteed...[]". 

They can’t spend $5,000 per month on marketing, pay $1500 for a professional web presence, pay $600 monthly for SEO; or afford to pay VAs to screen responses.

Anyone with a LT lease in place who has collected either two months rent or security and first months won't get tagged for vacancy. 

This is their web site: https://everseal.com/They describe it as a quartz-based product, but don't go into details of exactly what is in it.

By leveraging our combined experience and Seth's market insights, we were able to secure the deal at a price that allowed room for renovations and a profitable resale, ensuring a successful investment.

I might consider them if I had no other candidates , but only with 2 months security deposit in addition to the rent.
