Before any of that she needs to work out how much to budget. Especially how much she can afford to purchase a house for.
To get in to the house she needs to think of purchase price, deposit, stamp duty, legal fees, old house = renovation costs
To pay for it she needs to look at her savings and monthly expenditure to see how much she can afford each month. This is not the same as how much she can borrow. She needs to factor in, mortgage payments, house insurance, life insurance, maintenance, bills, car loan, credit union loan etc.
I'm sure any bank has a brochure/website detailing all the items that need to be thought of plus the steps in the actual house purchasing.
