Having a plan in place for dissolution or contingencies is a huge help.

Also assuming the above isn't in the contract, the plaintiff could seek an attorney to take it on contingency. 

I'd ideally like to see a contract with an income contingency that is provable, e.g., I'll buy your home for $2.5MM with the contingency that you can prove it makes $30K/month. 

Tell the seller you will sign a purchase agreement contingent on you being able to get title insurance.

@Jonathan BeaumontIf you had an appraisal contingency in your offer to purchase then you have the option to negotiate and back out if you don’t come to an agreement.

With a contingency of increasing interest to 18% up to an additional 24 months How did you add value to the deal?

It's part of the inspection period and contingency. 

No contingencies?

The plan with the cottages is short-term vacation rentals, and since this whole short-term (airbnb) style of renting may be getting pushed out in the future, our contingency plan would then be to turn them into regular rentals, or to sell them if vacancy ever became a real issue.

I am a buyer under contract on a property with all contingencies on track to be completed.
