Hi - forgive what is probably a very naive question but I'm just dipping my toe in the water for the first time!

I've been thinking about starting a cafe for a long time now and the time has come to do something about it. I will see a financial advisor shortly but wonder if someone can help in the meantime.

I have negligible savings to invest in the project so would be looking to raise money from the bank. I have a relatively small mortgage but a large amount of equity on my house and I'm wondering if there is a way I can release a small amount of that equity to invest in the business, without signing my house away? One option would be to remortage I suppose but given I expect to to hard pushed for money in the first year, I don't really want to increase my mortgage payments too much. The term 'releasing equity' comes to mind but I don't really know the implications of that.

Many thanks!
