Couple (19) seeking apartment in Poole

Me and my partner are currently living in temporary accommodation after living together for almost a year prior in a house share. Unfortunately due to landlord wanting his home to himself. My partner has a rare autoimmune disease and currently is waiting on cardiologist for a separate issue. Our current situation isn’t good for my partner due to having to share facilities. The only income me and my partner have as of currently is her personal independence payment and our joint universal credit claim which I am down as her career. I was previously in employment before we found our selves homeless but due to our situation I had to leave work and care for my partner. I’m hoping to return to full time employment once we’re able to find our future home. We would have to go through the council route of things where they would help with first months rent etc. Our monthly budget including bills would be £900- 950 whereas without bills would be £700-£850
