Financing in Mexico is not the same as it is in the US or Canada. No bank in the state or Canada will give you a loan to buy a property in Mexico. So, you have to look at your options.
Let us keep in mind that owning a property in Mexico is a dream. Not a really a necessity. It is usually a second home. A home away from home.
Most people that buy a property in Mexico do so by paying cash.
Financing is available through a private lender in Mexico. However, you must be ready to pay higher interest rates of up to 14%
In most cases you are only given up to 60% of the total value of the property you want. This means that you still have to come up with 40% of the total value.
