I know there are a lot of variables, but ball-park figure, that includes time spent on loan application, negotiation etc? 

Keep the ball rolling and move on to your next project soon. 

This would be a good starting point.I found it a helpful exercise for me and one you can always re run on a quarter or annual basis and you'll always be able to identify the low hanging fruit in terms of cash flow markets. 

I've heard from several investors that banks virtually never exercise this clause and demand full payment. 

If the bank finds out, they can exercise the "Due on Sale" clause and foreclose.

When dogs are not properly exercised, the will often result to destructive behavior.

I am definitely nervous yet excited to get this ball rolling!!

Reach out to them by phone call....not text....and ask them who the property managers are that they recommend to clients.Lemme hit you both with a curve ball.......Screw the phone call & the text message....Hit them with an email!

Another trick is to place a ball on the floor and see if it rolls in any particular direction as that can be a sign of sinking foundation, failing beams or joists or buckling due to water damage.From there, you need a professional to evaluate your findings.

The point of this as an exercise is a little different though.
