Can i get another mortgage by using equity of first mortgage as a deposit

Yes. You're selling 1st property aren't you?

Or keep your first house? Then it's a no

You can have as many mortgages as you like if you can afford to pay for them,

The same means test will be applied to the second mortgage as it was to the first. The difference being that you have the first mortgage to pay which will reduce your ability to repay the second one , which in turn reduces repayment capacity which reduces how much you can borrow.

which is what I was saying in my other post with regards to PTSB , they took some of the potential rental income from the first property already owned into account when they were calculating what I could borrow for the second house.

so it all depends on your income and outgoings really.

you need a cash deposit ,there is no way around that really.

if you earn enough to get a second mortgage from a bank then save the deposit.

Equity release/remortgage/borrow money basically all mean the same thing, you just want to borrow more against the property unless by 'remortgage' you mean move to another lender.

Some banks do extra borrowing against a property but it can be restricted to renovations to that property. To get what you want you would need to take out a new mortgage/remortgage/get a top up (whatever term you like to call it) to basically increase the mortgage on the first house to give you the spare money as deposit on second house. I'd ask a mortgage broker if I was you as if your income is high enough for both lots of borrowing then a broker should know which if any lender is likely to allow the increased borrowing on first property for this purpose.

Common back in the Tiger years obviously as was cross securing on both properties but obviously even though prices are back there again lending practices are not and are more restrictive.
