Nali, I have more questions for your question: Are you temporarily unemployed? Plan on going back to work? If so, what is the hurry to buy a home will all of your cash? Why not find employment and use the income to qualify for a typical mortgage? Given the low, low interest rates and the fact that you could invest your savings AND have potential tax benefits as the result of a mortgage, I would strongly recommend yo get some unbiased answers from a financial planner or accountant/tax specialist.
Asking a real estate agent and mortgage professional if your can, or should, buy will usually net you a flurry of "Of course!!! comments. We are, after all, in the business to generate and close real estate transactions. However, there does come a time to step back...and really question whether buying immediately is in the buyers best interests.
Best of luck to you!!! Do be aware that prices of real estate are not rising sharply...particularly in areas when one might find a home for $50,000.
