Hi @Zhong Zhang I have used vacancy hacks over the years to get personal properties under 1% when turning tenants over. 3% increase depends on renewing or getting new tenants, when renewing tenants that's  a safe amount.

I have some experience here, and my answer will be it depends. 

Just depends on the situation/scenario.

It all depends on what your requirement for cash flow is.

It helps to make connections with your local flooring, tile, kitchen design studios depending on how high end you want to make your flip depending if it is in a HCOL neighborhood.
