I want to know if it makes sense to buy a rental property as a sole prop, would it help me when i file taxes as i may be under loss based on income from property may be less than expenses
Purchasing properties under a legal entity only really provides asset protection (at a whole bunch of costs). So, whether you do it under your personal name (i.e. sole proprietor) or under a legal entity (e.g. LLC), your taxes will look the same.
Thats the short of it. Does that help?
