Every living unit must have at least one (1) bathroom which includes a flushing toilet, lavatory/sink and a bathtub/shower.

Obviously if you have a leaking sink cabinet that is bad you may want to replace.

For you folks not in Texas, what John means is "CD" areas where there's not great schools and not the best crime rate, don't even bother doing a lease optionIf you want to deal with nice owners that are intelligent, well-educated, they want to sink their feet for five years or more in a good neighborhood, good schools, go into "AB" areas and go after expireds, landlords, listed houses, for sale by owners, and talk to "we buy houses" people that have leads that are thrown away due to low equityIf you get the product right meaning a four bedroom two bath, quiet street, something that people really want, then filling it with the tenant buyer is quite easy, and making your 3 to 5% is a lot easier if the product is rightThink of it like the car business: you've got a Ford Fiesta on a car lot, and a Toyota Camry.

One of the tips my mentor mentioned was installing an unique bathroom sink to make your property more attractive toward potential tenants.

Yes I am picky, but I also won't be dealing with cabinets falling apart or leaky sinks if I do it right the first time.  

If you screen well and get good tenants, hopefully you won't have to sink a ton of money into the place when turning it over. 

At least 1 vacant stall won't sink you, and the location would easily fill the vacancy.

I think sinking 300K all into one spot that only generates 1700/month is too much risk for too little return.

However you can tell that the underlayment has rot or in places and is sinking in.

I just had one go vacant after a 6 year tenant and I had to sink about $8K into the property.
