7-8 months of runway is too little, at least for me personally (I'd be afraid to go do something like this without a longer runway). Move to shared housing first, to extend your runway to 1-2 years first would be my suggestion. Also, try to find some part time development job (you can tell the company that you are working on bootstrapping your own startup but are able to work for 20 hours or so per week for them as consultant). This will give you some safety net and some income, hopefully enough to just break even while living in shared housing so your runway doesn't decrease too fast. It's unrealistic to have any meaningful revenue in just few months, expect about 2 years for that in case your SAAS app takes off and you will also need to invest a lot into it in the meantime (infra costs, marketing etc).
