Exterior doors in a rental

[Matthew Brill]

I just bought a triplex in South Florida as a house hack. One of the units that will be occupied by a tenant has an exterior sliding glass door that opens to the backyard that doesn't close or lock appropriately. Am I better off repairing the sliding door or installing a different type of door (maybe French doors?) that might cost more but require less maintenance?

What are your thoughts? Are there any specific doors that you would recommend?

The units also need new front doors. With all the different front doors out there is there any specifications I should look for? Recommendations on locks?

Thanks!
