Specify for the next ten tenants
Porcelain tile or good LVP rather than carpet. Semi-gloss or satin paint in one colour throughout, so a touch-up needs one tin and no colour matching. Solid-core doors, standard hardware, and fixtures a plumber can source anywhere at short notice. Anything bespoke becomes a problem the first time it breaks.
Where the money returns
Kitchens and bathrooms let a unit at a higher rent. Flooring reduces turnover cost. Beyond that, spending tends not to come back in rent.
Where a rental property renovation returns the money
In two places only. A kitchen and a bathroom let the unit at a higher rent, and durable flooring cuts the cost of every turnover after that. Past those, a rental property renovation tends not to come back in rent, however good it looks. Owners get more from spending the same money across two units than from taking one to a standard the market does not price. Any contractor you use should be checkable at the Florida DBPR.
What rental property renovation should standardise
Everything that will ever be repaired. One paint colour throughout so a touch-up needs one tin and no colour matching, standard hardware, and fixtures a plumber can source anywhere at short notice. Anything bespoke becomes a problem the first time it breaks, on a property where the person who has to solve it is not the person who chose it.
Tenanted or vacant
Vacant is faster, cheaper and produces better work. Working around a sitting tenant means restricted hours, protection everywhere, and a schedule that will slip. If a turnover is coming, wait for it.
