Your wife can take as long as she wants to answer your offer to delay the sale of the house unless you contact her (lawyer) and say that the offer is not available forever, and you would like an answer by a date that you specify. If you agree about the parenting part and can get a parenting plan signed, then you could work out the assets and liabilities at trial. How long that takes is a matter of the amount of assets you have and whether the income is earned by a business or w-2 earnings. Also, you will have to go to pre-trial conference and then get a trial date set.
This communication is not intended to create an attorney/client relationship. It is always recommended you consult an attorney in person to discuss your case. Leonore M.

It really depends on how complex the case is. Most divorce cases can be tried within one day, whether that only be an hour or several hours. A case could last longer if there are multiple witnesses testifying, significant assets to be divided, and lots of evidence to go through.
This is not to be considered legal advice nor does an attorney-client relationship exist.
There are really no time limits on these types of things. You should formulate your offer in the form of a non-threatening and respectful letter outlining your proposal and indicating that if she does not respond within a certain time period, you will assume that she is not interested and proceed accordingly. There appear to be a lot of issues to your case. Settlement language should usually be drafted by an experience family law practitioner. Be careful of potential tax consequences of your offer.
