Exterior motion detector lighting repels all kinds of vermin at night as well.

We want the property to look uniform and to ensure it is well taken care of for the benefit of all the residents and as a good member of the neighborhood.For our SFRs we require tenants to take care of the landscaping to our standards or they must hire someone to do it.

You can help with this by providing a well lit property with motion sensor lights, on-site parking if possible and good fencing where applicable. 

It will be pretty uniform among DSCR Lenders - if the property is in a flood zone, flood insurance required, if not, not required

Unfortunately, eviction (unlawful detainer motion) is the only way for a landlord to regain possession of a property when a tenant refuses to leave voluntarily. 

All lightbulbs have now been replaced with LEDs, Photo cells have replaced timers, motion sensors have been added to all offices.

I can't imagine that part is super accurate but you never know...I have long wanted an IR motion detector that could essentially do the same thing but I've not found anything cheap.

Appraisers use a system called UAD (uniform appraisal dataset).

If you have ever bought a HUD house you would understand that HUD works in uniformity any chance it gets. 

I'd find a Qualified Intermediary now before you put things in motion to understand all the ins and outs.
