No, you should not. Chances of it working out are probably slim. You probably don't need funding, as many solo founders can attest. Hiring should be done once the business is already generating an income, and should be scaled based on that income.

What happens is that if you do sell your house, (assuming you'll pay rent) things will get a lot more stressful for yourself financially, and this will severely hinder your mental performance and chances of success.

An even better idea would be to get a regular job and bootstrap your business in your spare time, on weekends. Once it takes off, you can quit the job and focus full time in it. Successful startups coming from this kind of environments are way more common than those coming from YOLO, all-in approaches you are thinking of. And this is precisely because of the way the mammal nervous system works. The ability to do creative mental work is severely impacted when under a perceived threat (financial doom in this case).
