I own a rental property in Seattle, so I am currently working out how to mitigate the risk created by the Seattle City Council's restrictive policies.

At the time I was advised by council that the contract was still valid and that I could force the estate to go through with the purchase. 

@John Barry and @Natalie Vane here is the article from legal council that I use in Florida, hope you find it helpful.

Planning Board members come and go and many operate like a high powered HOA and you have to sell them on your plan so they will recommend approval by county council.

I'll add that I live in British Columbia.

Not sure if your association has legal council.

My name is Andrew I am a British expat, living near Cincinnatii, Ohio.

@Joel Owens @Ryan Jenks  just to add to the conversation from personal experience.I have two collogues that against my council  sold there perfectly good west coast multi's to try to scale up in units and go down in asset class.one bought C to probably D in Memphis rubbing their hands together at the 15 to 20 cap they were going to get.. they lost 400k in 18 months on it and could not exit quick enough.. only locals can handle those.the other sold her PDX 60 unit for a 5 cap made 700k... bought 300 unit C class in Oaklahoma city. because of the 10% cap being touted.. and after the managers and maintenance folks stole her blind guess were she had to move to. it was her entire net worth wrapped into that property.. 5 years later ( took her that long to stabilize and get decent enough books to exit for what she paid for it.) she sold moved back to PDX bought a 20 unit and condo on Maui  LOL...

The city council is voting on whether to do a road diet on Parkwood in just a couple weeks.

From his perspective, he would need to work it out with her, perhaps via their legal council.
