I have ADHD and have been in your financial position. I'm married with 2 kids. Last year I bought a house for the first time, I'm in my 40s. This can be fixed.
My advice is very similar to others on here and, apologies if this has already been said, but you need to deal with this now and put saving for a deposit to the back of your mind for the time being.
- You don't have any spare money to save so it's not going to be possible right now anyway
- You need to get a handle on your debts as it's spiralling
Today you need to spend time looking into all your debts, getting the balances, monthly repayments and APRs. Put all this information into your spreadsheet along with the agreement numbers.
Then you need to go through your bank statements and take a note of ALL your outgoings (bills, subs, groceries), you can likely export your statements as an excel document and tidy it up from there.
Finally you then need to go onto the Step Change website and start a no obligation assessment where you plug in all the info you've gathered above and your income. They will then suggest potential solutions, all without speaking to anyone at this stage or setting the ball rolling.
They will ask you what you spend annually on clothing/gifts/hair cuts etc. Do not panic about this if you don't know at this stage. Just give rough estimates, it you under estimate a prompt will come up saying it doesn't sound reasonable and you can amend.
You are under no pressure to proceed when doing the assessment, I sat on ours for a few months and tweaked it when things changed before I progressed it. My situation was different though as I knew there were financial changes coming up for me so we were waiting until they came into play before proceeding.
When their assessment tool has calculated everything you will be left with a "surplus" which is what they have determined is what you have left over to service your debts. This means it's really important to make sure you don't under estimate how much for school uniforms/present buying/entertainment etc.
Finally, you mentioned concern about going into something formal because of wanting a mortgage. Kindly, you have a CCJ and at least 1 default already so your credit rating is sub par as it is.
Getting a handle on this NOW will free up disposable income for you and your family and take the metaphorical noose from around your necks.
Good luck.
