My first property

Hey guys,

looking at getting in the game but just gathering info and research

im looking at becoming financially free the earliest or safest way as possibly

i had someone advise me to do a interest only loan for 7 years to make the most positive income and gain equity. But I do realise after this time the repayment will be higher but then I’ve been told to do a refinance for another 7 years.

i have multiple questions once let’s say the equity goes up after 7 years would it be best to refinance for interest only or to go P and I? After 7/14 years equity goes up would it make sense to sell and if I was too would the debt be for the initial purchase price?

any advice about this or anything in general would be hugely appreciated
