Totally normal, welcome to being a landlord 😅.

I do believe the post Pandemic boom of new investor interest has returned to normal levels as of late. 

Or is this a normal part of the process, and I should only be worried if they can't produce the warranty?

New tenants have the normal 30 to 60-day delay.

Offer the Fair Deal: You can say, "If you pay the last month's rent as agreed to, I will return your security deposit promptly, minus any reasonable charges for damages above normal wear and tear, after you move out and return the keys."

Then sell the property and do a 1031 exchange, which would allow you to invest in another investment property with some better potential for cash flow and appreciation, using the tax you would normally pay.

In terms of what you paid, if it was a normal and legitimate company it's hard to say.

I go with the Ohio law & I’ll leave the basics. the other leases i’ve read, some good stuff i take, some bad stuff i leave. i wrote down the extra stuff & stuff that will protect me (financially & personally). you will end up going over the lease many times over the course of ur real estate investing, that’s normal. get to a computer & start typing.

You don’t hear about a syndication for normal private equity business investing, which could use a SPV structure to invest into one company.

I normally model two sets of financials.
