I thought about resubmitting with a small non-refundable deposit.

@Alex ThomsenThe standard NC contract (2-T) has two different deposit options.

Personally, I would keep the deposit out of the conversation.

My inherited tenants ALL SMOKE and none had security deposits. 

I usually charge a pet deposit and monthly fee, but from my limited research, believe I cannot charge for a service animal. 

But get them and the family staying in the home both on the lease since the insurance is paying the rent, but the family is usually responsible for the deposit.

People like to ridicule what they don't understand, but when the government inflates the dollar away, or taxes whats hiding in your safe deposit box, or we do a bank bail-in like Cyprus did, THEN maybe some people will bother to read a few articles and learn about Bitcoin.   

Worst case deposit money at each bank and earn.  

For example, when I take on a rehab I typically deposit the budget into a separate checking account solely for that rehab and pay all the rehab expenses from there making it easy to identify in my bookkeeping.

Quote from @Julia Lyrberg: If you pay cash, you'll own it free and clear, which means instant cash flow and no mortgage to worry about.
