The income level necessary is relative to the mortgage amount you're applying for.
But in your case, you're going to have a tough time getting a loan. No lender is going to approve your spending 50-60% of your income for housing. They're looking for you to land around 20-30%. What you're spending for rent now far exceeds the recommended ratio of housing cost to income.
Also, owning a home is about way more than simply making a mortgage payment. You need to be able to pay for upkeep and repairs. A single appliance can cost more than you have saved. If your HVAC dies or you need a new roof, where are the thousands of dollars for those repairs going to come from?
There are plenty of rea$on$ why it makes sense for some people to rent and let their landlord bare the costs of repairs and upkeep than to take that risk on themselves.
