House hunting and looking

I’m reading with interest. Looked at two properties this week that have been rentals for many years. Renters have been groups of people not families with turnover of roommates every few years. The owners (family) want to sell. We are local and my husband will decide what should be done. The flooring in both is terrible. Stained carpets that need replacing. I’m getting the consensus that it’s best to replace the entire house with the same flooring.
There are two ways of going about this process, one would be to sell as is and let the new owners do the fixing up. The other is to paint inside and out and replace flooring and maybe new vanities. Not quite turn key ready but clean and livable.
