Second mortgage loans do not affect financial aid.
Second mortgage loans do not affect financial aid at all. Of course, there are other financial implications with taking out a second mortgage and financial aid to fund an education at the same time. However, whether or not you have a second mortgage on your house is unlikely to make or break the amount of financial aid - if any - that you receive.
There are many types of financial aid that you can receive. For example, some states offer services to students who are residents or that are attending school in that state which other states do not offer. However, there are a couple of basic types of financial aid that most students are offered if they decide to apply for them. Therefore, let's go through those types of financial aid and the affect (or lack there-of) that a second mortgage could potentially have on these types of financial aid.
Students usually try to apply for scholarships and grants first because they never have to be paid back. Grants are based on your financial need, so a second mortgage is not going to affect it. Perhaps if you have a second mortgage, you really do need the extra money. Therefore, if it affects your grant, it might do so only in a positive way.
In the case of scholarships, those have absolutely nothing to do with a second mortgage on your home. The only thing that scholarships have to do with is achievement at some level, whether it be through academics, sports, arts, and so forth.
Some students choose to engage in a work study program, where they hold an on-campus job but all of their earnings go towards their tuition. Work study programs are based on need, as are grants. Therefore, a second mortgage on your home is not going to prevent you from getting approved for a work study program.
Loans will depend on who is taking out the loan. Sometimes parents will take out a loan, and you might run into trouble if your parents have a lot of debt in their name. You might have issues getting approved for the loan, but that will all depend on your exact financial situation. Maybe you will want to consult a financial planner to help make these types of decisions.
However, if you are taking out a student loan, a second mortgage on your home should not affect it. Be careful though, especially if the second mortgage is your own. You do not want to get so far into debt that all of your money goes into paying off other people. Remember, if the mortgage is not paid, your house or your parents house could be taken away from you or them.
