You said your wife could potentially get approved on her own, so did you ask what type of terms you'd get approved for if your income was considered vs. just your wife's? If there isn't a difference, then it sounds like you are just trying to find a lender based on the principal of using your income to qualify... so potentially you could be relegating yourself into using 1 particular lender rather than having multitudes to choose from. $70k/year of income to qualify for a $150k mortgage sounds pretty do-able, depends on what her other debt payments are though.
A job offer alone isn't sufficient to use to qualify in any situation - however a signed employment contract can be used in conjunction with Fannie Mae or FHA mortgages. Not all lenders will abide by it though, as it's pretty risky to use income from a job that hasn't begun yet in order to qualify, as proof you've received income is needed before the loan can be endorsed by FHA or delivered (i.e. sold) to Fannie Mae - and that is where most lenders have a problem because they don't want to hold a loan on their books for a period of time before it can be endorsed or delivered.
FHA guidelines are:
Projected income is acceptable for qualifying purposes for a borrower scheduled to start a new job within 60 days of loan closing if there is a guaranteed, non-revocable contract for employment.
The lender must verify that the borrower will have sufficient income or cash reserves to support the mortgage payment and any other obligations between loan closing and the start of employment.
The loan is not eligible for endorsement if the loan closes more than 60 days before the borrower starts the new job. To be eligible for endorsement, the lender must obtain from the borrower a pay stub or other acceptable evidence indicating that he/she has started the new job.
Examples: A teacher whose contract begins with the new school year, or a physician beginning his/her residency fall into this category.
Fannie Mae guidelines are:
Employment Offers or Contracts
If the borrower is scheduled to begin employment after the loan closes, the lender may, depending on its risk appetite, use the borrowerâ€™s offer or contract for future employment and income to underwrite and close the loan. If receipt of the income or employment information cannot be obtained prior to delivery to Fannie Mae, the loan is ineligible for delivery.
Verification of Employment Offers or Contracts
The lender must obtain the borrowerâ€™s offer or contract for future employment and anticipated income. The lender must determine whether to close the mortgage loan prior to the borrower beginning the new employment.
The borrower must begin employment before the lender delivers the loan to Fannie Mae. The lender must obtain a paystub from the borrower that includes sufficient information to support the income used to qualify the borrower prior to delivering the loan. The paystub must be retained in the mortgage loan file.
One lender we work with has guidelines which say:
For borrowers that wish to close prior to their first day of employment, the borrower must have an irrevocable employment contract with a professional position. The borrower must begin employment within 45 days of closing. All employment contracts will be considered on a case by case basis.
Another has guidelines which say:
â€¢ Maximum 80% LTV
â€¢ Purchase transactions only
â€¢ 1-Unit Primary Residence only
â€¢ Borrowerâ€™s employment contract or letter is obtained
â€¢ Borrowerâ€™s written acceptance of the offer is obtained
â€¢ Time frame between Note date and commencement of employment (employment gap) must not exceed 90 days
â€¢ Borrower must have adequate cash reserves after Note date to pay monthly PITI during employment gap PLUS 3 additional months reserves
However if the terms your wife can qualify for would be the same as what both of you would qualify for, to make it easier on yourself I'd recommend you just proceed to qualify with her income and not try to use yours.
