I imagine Liam would have a better idea about this, however yes, there is certainly every possibility. As far as I know banks frequently accept equity as a 'deposit', however Loan to value ratio on investment properties (they will have to term the second property as investment, regardless of the rationale behind the purchase) would probably have to be below 75% ie. with 80K equity the max you would get would be 320K (in total ie you would be advanced a max of 240K). Additionally the normal income requirements would apply.
