Since the state defines housing as a critical need and since brokers by contract have a "fiduciary responsibility" to their clients, there are still a (surprising) number of showings happening, particularly under $1.3mm and in the lower end of the market. If you are under contract, inspectors/appraisers/title/lenders are all working, so it is full steam ahead.
The Colorado Association of Realtors just created a COVID-19 addendum, which will give some leeway to dates/deadlines. Contact us for more info.
Sellers: Although real estate is included in 'essential services' in CO, many sellers who are living in their homes are choosing to wait to show/list their homes until we're through the shelter-in-place. Vacant homes are being listed/are easiest to "safely" show. There is a general agreement that Days on Market (DOM) will not carry the usual weight for at least the next few months.
Buyers: Some buyers are submitting offers on properties site/sight-unseen, then seeing the property when under contract. (We had sight-unseen offers in 2014 and 2015 also, due to low inventory.) We are continuing to experience some multiple offer scenarios from $500k - $1.25mm. Broadly, buyers, if it is possible for you to house hunt online or virtually until after the shelter-in-place is done, it will be safer for everyone and our economy will rebound faster.
