I think you will make much more money renovating as most people cannot envisage how a unit will look done up, but why not do one up as a display unit, get a valuation on that, then you can sell it and proceed with the next one so you will not be without all the rents at once. The trick with renovation to sell is to only do some big basics, new carpet or polished boards, a paint and some new wood venetians from a cheapie home products store like Freedom.
