I’ve worked with a few tools for property intel, and while no service is 100% accurate, some options have stood out for specific use cases:BatchLeads: They offer a solid skip-tracing tool with good accuracy and detailed reports.

Yes, it's true that you might be able to find a product you need at a greater discount when a brand like Wayfair or CB2 is having a sale, but I've found that they truly do offer superior discounts at scale, even considering the fee. 

I got no other offers in the 45 days it was listed.

Your maximum allowable offer. 

If I were going to buy in FL I would get to her class if still offered.

INstead of just saying "no" we asked them to check with their credit card company if they offer travel insurance yada yada.. we got a 5 star review form them without giving a refund.

I have gotten a seller's credit for my 3 existing units but to be conservative, I will assume I am paying full closing costs here.At the moment, I have ~$25k in a HYSA and expect to save another $10k from my W-2 before I start putting offers in.

You will find that lenders will reach out to you and try to ally alongside you (I know I have received a few emails and phone calls from different lenders trying to offer their services) but few are willing to 'teach' you.

Also send me some details on your service offerings, I am potentially looking for a new tax accountant.

IMO what will make your company successful is the value you offer to your owners/clients & your tenants.
