I went to the website and printed out the application and mailed it in.Later he sent me a text letting me know that he didnt get my application.

They will need the account numbers anyway (to verify that you are actually the account holder), so you can hide them, but you will have to give it to them on the application.  

Typically I charge one months rent, and will handle applications, credit and reference checks and all showings.  

(or visa-versa with you as the purchaser using a mortgage personally).  

The reason for it is I am living in Australia (Australian resident) which my wife (US citizen) and we are moving to Temecula this year but we may be delayed with our visa.

You will want to check local law, but in my jurisdiction an UNLICENSED person CAN do the following:  Delivering a lease application, a lease, or any amendment thereof to any person;Receiving a lease application, lease, or amendment thereof, a security deposit, rental payment, or any related payment for delivery to and made payable to the real estate firm or owner;Showing a rental unit to any person, or executing leases or rental agreements, and the employee or retainee is acting under the direct instruction of the owner or designated or managing brokerProviding information about a rental unit, a lease, an application for lease, or a security deposit and rental amounts to any prospective tenant; orAssisting in the performance of property management functions by carrying out administrative, clerical, financial, or maintenance tasks.The key is in how the money is handled. 

The uptime and speed of the application has been excellent. 

Based on the use and definition of the term "deposit" in legal contracts, the modifier "non-refundable" is not applicable.  

PROPERTIES LISTED FOR SALE For a rate and term refinance transaction, the borrower must evidence that the listing has been cancelled, and must not have been listed for sale as of the date of the application.

To get this, you have to fill out an application, pay a fee and have an inspection done.
