Quantify them and ask for a reduced price. 

I like the idea of identifying the sellers needs and reasons before quantifying my interest or opportunity.

What's interesting about this is the use of the word speculators, because if there's a quantifiable increase in value based on changes made to a property based on mathematics and past personal experience, is it really still speculation?

It's fine to get a rough idea by using square foot guesstimates but before you make an offer I would suggest drawing the project as complete as possible and then quantifying everything so you can put a unit cost to it or send the drawings out to bid for the scopes you need help with.

@Justin Gottuso you really need to quantify your goals and that will make your decision easy.

Appreciation is NOT a quantifiable goal so I don't factor that into my decision to buy property.

Stock market losses will add to the chaos creating a new batch of opportunities.Oil Price collapse impactWill further depress housing and other aspects of localitiestes with oil dependent economies.Conclusion: corona virus and oil price impact will take billions out of economy, impact can be predicted, quantified and opportunities could be generated. 

Prove there was quantifiable monetary damages;3.

We just don't know and that is risk which is unprecedented and hard to quantify for me at this point.

Thank you for quantifying how hard this might be for your bank account, we will all pray for you and your millions of dollars.
