maybe this sounds stupid.
i've been to the bank recently asking for a mortgage deal ,however couldn't borrow enough money for the property i want.
is it possible to take out two mortgages from two companies at one time?

you can't have two mortgages at the same time. You may have one loan (small amount of money )and one mortgage.

Your lender will keep the deed of your property, and you will only have a copy of it. You will get the original deed back only when you have paid all your mortgage. Therefore, I don't know how you can work out when there are two mortgage lenders and only one original deed.

If you can't get enough mortgage for your wanted property, it means that you can't afford the property at the moment. To be realistic, maybe you have to buy an affordable one.

can take out two mortgages BUT NOT at same time

或者这么说，同一个房产不能有两个MORTGAGE
如果你同时拥有多个房产，只要你还的起，当然可以有几个MORTGAGE啦

if u want a mortgage,once u find the house,the bank will send a surveyor,the survey will tell the bank whether the house is really worth what u offer to pay,then the bank works out the risk,so if they do not see the house ,u will not ge the money,and when u ask for a mortgage,they will ask u do u have another loan or mortgage,I do not think lie is a good idear,they will find out one way or another.
