Sorry to hear about your husband. I hope he is recovering well.Is there any chance that her school will help?

I think you should put a little bit more about you and what you are planning to study.

Buy to let mortgages

I think it is wonderful that you are willing to learn. It is never too late. Check your local authorities, they often have courses available free of charge for people going back to work. Sometimes if someone gets financial help to pay mortgage  it works in their favour, but if you don't, looking for a job and need to update skills may be just as good reason.

It is difficult to offer a job without knowing anything about a person. Try to say more about you skills and your abilities, why you want to do it as pay your bills, mortgage  or help your family.

Did you check  government  loan? You may qualify for one. It is a mortgage in a way, but not with private lender, but with the state.

Did you try to ask any help from government for your mortgage as there should be some housing help available.

Try some simple solutions. Free take away delivery in your area, special menues and discounts to attract more people. If you have a commercial mortgage check if refinancing will save you some money.

Try speaking to a charity which is specializing in your condition. It is really worth giving it a go and I know people who were offered help with mortgage costs and other bills. 

I think you can get a grant to restore an old listed building and you should qualify for a mortgage  as a veteran.
