Even if we are told not to worry about financing, we worry nonetheless especially when an accepted offer on a house that we love is on the line.
While nobody can guarantee 100%of the time that you should have absolutely no worries about the processing of your loan, most of the time, if you are dealing with a knowledgable and professional Mortgage Consultant that you trust, then you shouldn't worry excessively.
If your husband has been employed at his current job for a year and a half and if you can document his previous employment for the 6 months prior, even if it was at a different employer or in a different field, then typically you should be fine. Of course, exceptions always exist and will depend on the particuar situation at hand, but typically you shouldn't worry too much. Sometimes, you might have a doubt when a person has been self-employed for less than 2 years and that person's previous employment or experience was in another field, etc. But, as I mentioned, this is where your trusted and professional Mortgage Consultant should be able to guide you in your options. It is very important that you deal with someone who knows what he or she is doing and that works at a financial institution that will have the underwriting flexibility that will deal with those and other types of situations.
