To understand an answer we must first fully understand the question. I echo Mr. Ken Jones and Mr. John Juarez comments.  

I will add, be careful relying on the information found on the Internet. 

Typical = 30 days.

But, I've closed them in 5 days to 60 days and some shoert sales took 6-24 months back in The Crash.

First...we must agree on what "execute" means. The definition below was taken off on the internet:

Definition of Execute

Noun

1.    To complete, and give effect or validity to, a legal document, decree, law, or judicial sentence.

2.    Fulfilling legal requirements of a contract or other instrument by signing or sealing.

So...you can see that, once a contract is written, it can take only a short time to "execute" the contract.

Yet, I do not think what you wrote is really what you want to ask.

If you are asking how long it take to complete a real estate transaction, that is not a question that can be precisely answered.

Some transactions, as in a cash purchase, can move to close in days.

Others, due to inspections, negotiations, financing, escrow processing and other possible delays can easily take 30 days or, in some cases, much longer.

Many contracts are written with a close of approximate 30 days in mind and work out satisfactorily.

An executed  purchase contract in real estate is a signed agreement by both parties to buy or sell a property. The buyer typically pays the seller an earnest money deposit that they will lose if they do not follow through with their end of the bargain, but it's generally 3% of the purchase price.

If you are talking about the close of escrow. The timeframe to complete the transaction depends on the contingencies listed in the purchase agreement.

If you are paying cash to purchase a home and have no inspections, appraisal, or loan contingencies, you can close as soon as your time company title can handle the job. I have sold homes in as little as 7 days.

30 to 45 days from offer acceptance to closing

Realize that with willing buyers, sellers and all the collateral help, the clause "time is of the essence" sprouts running legs. From days to weeks or an easy 60 dayer, one must always finish what they start. Is sooner better? subjective

3 days for a miracle closing to over a year when issues arise with title. After 60 days the longer it takes the more likely the buyer will walk!

There is no typical.

Though your terminology may be off, I would assume tht you are asking about the period from ratification to close.   5-6 weeks

If you mean how long does it take to close, I'm sure it varies by state and area. Here, we can close in a week or two if someone is paying cash, 3-4 weeks if they're getting a mortgage, and sometimes as long as 45-60 days. It is all negotiable. Both parties have to come to an agreement and the supporting vendors (lender, attorney, etc.) have to be able to follow through. Having said that, the majority of our closings seem to be 30 days in this crazy market. Prior to this crazy market, 45 days was more of a standard. If I'm working with a seller, I try to let potential buyers agents know the sellers desired closing date. If I'm working with a buyer, I call the listing agent and ask what the seller's preferred closing date is. 

executed is signed and that's a matter of minutes, hours or days depending upon the market and negotiations.  If you really were trying to ask how long from binding agreement  to close 30 to 45 days and again it depends on the market.  Right now appraisals are slow in our market because we are so busy.
