I have used Equity Multiple and I have not had any issues to date.

The online realtor sites give you dates but they are usually in the past and always have a disclaimer that " Auction time and dates can change".

Just let them know if they are not willing to sign the lease with the increase that they will need to leave by X date. 

But, putting the property in a Land Trust, in your brother's name, and then having him tfr the beneficial interest to you at some future date (maybe after letting the lender know of the trust tfr), may help shield the beneficial interest tfr, but technically, may not circumvent the DOS.

The only difference is the seller is behind on payments, which is irrelevant if the sale covers all the debt and can occur before the foreclosure sale date. 

You don't know how the process works so I don't know why you think you would be getting offers accepted without a pre-approval or proof of funds.You get a pre-approval with a lender you know and every time you make an offer, you just have them adjust and confirm the date and the new property address.

A good deal is a good deal.Imagine if you tried applying time lines and readiness to dating?

I have a couple weeks to the court date, and if I can extend that it may give us time to resolve this.If I need to pay more than my share is there anyway to recoup this when/if the house is sold?

A underwritten lender Pre Approval provide sellers with greater assurance that the borrower can close as well as an option for accelerated closing date timeline.

The data that is publically available is the price the home was purchased, the date the home was purchased, and the mortgage terms.
