Quote from @Chris Lo: Which platforms/websites do landlords use to find the rent rate, how long the rental properties have been on the market, and all the details about other rental properties?

Listing on multiple platforms does affect ranking by platforms but not as much as you think.  

What if something changes with how that platform works?

Without going into too much detail, my current situation stems from selling a previous company via partial owner financing, only for the new owner to default on the purchase, leaving me in this position.For traditional financing, I understand I’ll need at least one, if not two, years of solid credit history, tax filings, and other financial documentation.

My question again stems around using seller financing to allow them to receive a consistent monthly pay of X amount and delay/lower their tax bill in the short term instead of going through a lender to borrow 800k+ causing my mortgage to be significant part of our income roughly 40-50% of take home -  which we are approved for LOL.

I'd stay on platform.

I know Shopify typically is a more commerce base platform.

Hi, I just started using BiggerPockets and am excited to learn about the community and all the resources available. I'm particularly excited to find others in my area and start to attend some meetup groups!

These platforms include RentRedi, Stessa, Avail, Innago, Apartments.com (formerly Cozy), and TenantCloud.Pretty much every platform mentioned contains the features you are going to need.

When you have employees promoting the platform like it is the best platform ever and free accounting services, it was going to go down sooner or later.Pretty sure their other services are going to go down shortly.Baselane is offering assistance I believe, but they are just like Azibo.
