If your husband qualifies for the loan alone, there is no need to worry.
The only reason it would be necessary to remove you from the loan would be due to your monthly debt causing your remaining borrower's qualifying ratios to exceed 45% on the 'back end'.
If your husband qualifies with your debt and his own income, there is no reason to remove you from the loan.
Should you become employed, the lender will require a copy of your first paycheck stub before they will fund the loan.
Good luck to you! :)
If you can qualify to purchase the home on just the one income, the seller will co-operate in making the change, as long as it does cause a lot of delays. Check with your lender for advise on this, but do not expect your change in employment status to go unnoticed. Getting ahead of the problem and disclosing is more likely to salvage the purchase, if you can still get the loan. If someone else discovers on the sellers and late in the process, your credibility will probably be damaged and they may kick you out of contract and remarket.
