@Chandirasekarendiran AnandanYeah, I know this is not always true, but if I see one partner not being on board with house-hacking, it's usually the woman, for obvious safety reasons.What do you think about a home with a basement that has a separate entrance?

Moving foward: 1) Enter into month-to-month leases instead of yearly (term) - they are the SAME to YOU but month-to-month give you all the leverage should this occur again in the future. 2) You should add a clause to elaborate on and expand on the current 'Noise/Waste' clause and the new clause should focus mostly on nuiscance and violation of other Tenant's quiet enjoyment and the remedies (fines) leading up to eviction if the issue is not corrected. 3) You should add a clause to protect yourself from the other Tenants (the good Tenants) ensuring to clearly spell out that you are not resposible nor do you guarantee that other Tenants will abide by the lease nor is it your respobility to enforce the lease vs. other Tenants, nor do you guarantee safety. 4) This is the most imporant one that will fix most of your issues: Because you are adding #3, you will now add yet another clause that gives ALL Tenants the right to enforce the lease in regards to your new 'Noise/Waste clause 2'  against any other Tenant who violates it and will idemnify you and hold you harmless, ensure to limit the right to only the pertinent clauses ---- essentially, if Tenant A complains to you that Tenant B is making funny faces at them... you can inform and remind Tenant A (in writing) that if the issue is a problem they have the right to pursue legal action vs.

I think the company is Safety First.

However, it's advisable to consult with a local attorney or property management professional to ensure that you follow the appropriate procedures and adhere to any legal requirements.Ultimately, the priority should be to protect your property from further damage and address any potential safety concerns.

We now prioritize conducting background checks, checking references, and reviewing their previous work.

To provide a bit of extra safety, I then later get the lockset rekeyed.Hope that helps. 

I mean the tenant should have to make some effort for their own safety.

There are some exceptions: if landlord can prove it causes undue financial or administrative harm to landlord; the animal is a direct threat to the health or safety of others (bodily harm)...

I've never had an issues, it's just an extra safety measure.  

Prioritize properties needing minimal immediate rehab.
