You might lose business.

I just had a buyer in Toledo lose one.

Fail at that and you are setting yourself up to lose money.Funding: This is also an essential part of the puzzle.

Redfin announced they were leaving NAR last year (but didn't actually leave because they couldn't in most markets or they would lose the MLS access that their platform is built on), and Zillow is still a NAR member. 

I'm not sure what to do in this situation, whether to drop the deal and lose my earnest money or try to find another lender.

Of course, have a plan to pay it back but it's a great way to utilize money that is basically tied up, and losing value since in a couple years it won't be worth what it is today.  

Therefore because of the low inventory there is it 0% chance that there's going to be a crash so if you are going to keep this mindset I would highly suggest you do research on what's really going on with regards to inventory because you're going to lose out big time.

Even going through the process of having all my deposits coming in a the beginning of the month and paying bills out of the AIO at the end of the month, wouldn't you be losing lots of money versus a 15 or 30 year fixed mortgage? 

I'm not sure what to do in this situation, whether to drop the deal and lose my earnest money or try to find another lender.

So every year you do not compensate by raising rents, you are losing money.
