I've recently started using Intellirent.com for screening, as it further automates the reference checks (only works perfectly if the employers and former landlords respond), but it includes an authorization form (electronically signed by the applicant) that you can download.

I don't know what you signed with the broker or what expectations were reduced to writing, I only know that IF you wish to have an open house and they refuse, and such authority to refuse such a request is not provided in your listing agreement, then you should have the right to terminate that relationship.

I will make her to declare to authority she has nothing to do with the lost check then I will do my part.

A taxpayer can generally claim that a rental property is ready if the property either receives, or is ready to receive, a Certificate of Occupancy (CO) by a state or local authority.

BPCON is a GREAT place to network, find accountability partners, learn from tons of speakers, meet your favorite podcast hosts and authors, and even close deals while you're there (it wouldn't be a first!) 

If you have extra taxes then you should absolutely account for them.Contact Vrbo, Airbnb and your local authority and see if they are automatically taken out or if you need to submit the extra taxes.

For example, if you are creating the LLC with more than one member, you should think about creating an operating agreement which will delineate the authority of each member; whether authority to manage the property will be vested in a manager; the process that more significant decisions are made (for example, will major decisions like whether to sell require a unanimous vote?)

The payment has a clause: By accepting this payment, I acknowledge and accept the following terms:I am the property owner (or an authorized agent for the owner) of the above-referenced property and I am authorized to receive payments.

Check out Cost Segregation Authority. 

The agent is generally not authorized to provide a buyer with any confidential information on the seller or seller's financing.
