There is a set time for the agreement, so if you can't give 30--45 days for the agent to find you the right deal, or don't trust they can/will, then move on to the next agent.By entering into an agreement with the agent they become your fiduciary, and as such will represent your best interests. 

The current owner listed last years income as $51,000, but currently has rents at (for the five separate units): $650, $750, $800, $825, $1125 (the math doesn't totally add up so maybe he changed a rent payment at some point). 

You can collect payment directly through airbnb or collect it through your payment processor (mine is Stripe) on your direct booking website. 

My main account has all the rents deposited and all expenses deducted such as mortgages, some utilities and an electronic payment app connected to the account to pay contractors.

Rent was due by 5th but no communication on late payment and is not responding to my text/emails.

I weigh more on making 3x rent and having great rental history of on time payments with no evictions, no lease violations or violent criminal history.

Even if it does, there's closing costs to consider.As I said, I have no cash myself, so I'm asking how I can deal with generating cash for closing costs (and a down payment) if it comes to it.The house costs $139000.

They have a balloon payment for the principal due in 10 years.

They are able to See a COC return within weeks of the down payment, when the unit rents.
