To verify that you're an experienced investor I may request that you send me a link to tax records of one of your investment properties.Thanks,jon.

(All are verifiable.) 

But if I try to get another loan from the same bank that gave me the first mortgage, wonder if someone in underwriting in process of verifying income against mortgage might raise a flag: 'why does one of our mortgages have a land contract against it...'

If you verify your accreditation via net worth (ie: $1M excluding primary home) then that's usually 3mo across most platforms I've invested in (including startups ie: angelco). 

If someone comes to me, I'll send them your way.If you need help in your search or want to verify something don't hesitate to ask.For example: I have clients worldwide and things are just as easy as I e-mail them, talking on the phone.

We haven't had the inspection yet, nor have I verified the seller's rent roll or expenses other than property taxes.

I'm not 100% sure, maybe someone else can verify if that statement is accurate.

Hi All, I am going to rent out our current house and wanted to check how crucial it is to verify with the current property management company for prospects.  

VERIFY numbers.

Remember the old adage of trust but verify?
