Lastly for you as a seller you could be collecting below market rents and the 1% rule might not apply to the listed price (compared to what market rents would be) so you’re listing agent is able to speculate on market rents (with comps) if it’s vacant to justify listed price.

In reference to @Peter Walther post about foreclosure, the following is copy & pasted directly from the State Bar of Wisconsin Form 11-2003 Land Contract:"Purchaser agrees that in the event of a default in the payment of principal or interest which continues for a period ofdays following the due date or a default in performance of any other obligation of Purchaser which continuesfor a period of days following written notice thereof by Vendor (delivered personally or mailed by certifiedmail), the entire outstanding balance under this contract shall become immediately due and payable at Vendor's optionand without notice (which Purchaser hereby waives), and Vendor may singly, alternatively or in combination: (i)terminate this Contract and either recover the Property through strict foreclosure or have the Property sold by foreclosuresale; in either event, with a period of redemption, in the court's discretion, to be conditioned on full payment of the entireoutstanding balance, with interest thereon from the date of default and other amounts due hereunder (failing which allamounts previously paid by Purchaser shall be forfeited as liquidated damages for failure to fulfill this Contract and asrental for the Property); (ii) sue for specific performance of this Contract; (iii) sue for the unpaid purchase price or anyportion thereof; (iv) declare this Contract at an end and remove this Contract as a cloud on title in a quiet-title action if theequitable interest of Purchaser is insignificant; (v) have Purchaser ejected from possession of the Property and have areceiver appointed to collect any rents, issues or profits; or (vi) pursue any other remedy available in law or equity.

Just got a property management company to get me renters and collect my rents.

Mahogany Bay Resort & Beach Club, Curio Collection by Hilton

The previous owner only collected cash so no proof of income.

I've sent about $5m to collections.  

We also structured the contract to have the seller credit us at closing the full collected rents, an extra year of taxes, and had the seller pay $7,500 in closing cost assistance.

How much can you collect rent annually if they are fully occupied?

With more detail: the 3rd party property manager collects the tenant security deposit from the tenant, and keeps it in an escrow account in accordance with all laws.
