Am I forced to pay in all cash?

[Andrew Giunta]

I have no income, but instead a lump sum of cash that I made selling a company. I am currently helping my mother get a mortgage so I will technically share around 220k debt with her, but I have 500k-1m im looking to invest into property. Are there any mortgages available that would let me not show income, but also arent a ton higher when it comes to the rate? I read something about some loans where if you have a 50% LTV they dont ask for income. What would you do in my situation, or is my only option to buy a few properties in cash, establish the income then finance more ?
