Composite door blank furniture

[waccoe]

Hi all,
Please excuse the really dumb questions, but I've got myself mightily confused by all this. I have a rental property, which my builder is currently in the process of refurbing. The front door is a fairly old timber door, which has a top light, which I want to replace.

In order to keep costs down, I've bought a "blank" composite door, which will be fitted to the existing timber frame, but I'm struggling to work out what furniture I'd need. I don't really want to go to the hassle and expense of fitting a multi-point lock, so I think I'd need both a mortice lock and a night latch? What I'm struggling with is the handle & mortice lock combo. If it's a mortice deadlock, I don't need a handle at all do I, and could just fit a centre door knob? Is that the best way to go? I prefer the look of a proper 92pz handle, but not sure how that would work with a standard mortice/sash lock.

If I fit a sash lock, to get in, you'd have to unlock the sash mortice lock then open the night latch, then hold down both, which seems unnecessarily convoluted.

Consider a 5 lever mortise lock with a handle,, plus another 5 lever mortise
lock below it (no handle) to prevent kick in as much as possible.
You can fit a night latch too if you want, although these don't resist break in particularly well.

Night Latches are prone to locking people out by accident, which maybe a consideration if the non too discernible tenant is happened upon! And they offer limited advantage anyway.
