When the property has electronic keypad locks on the exterior entry doors, is it required (by law) for the landlord to also provide the tenant with a physical key?

Ultimately I spent $250K on College to emerge with a Doctoral Degree in Physical Therapy. 

Lost rent to vacancy often costs less than physical depreciation in terms of actual cost to repair and property value.The people who let it all go and continue to collect rent do so as an effort to pay for their sanity, not because it makes the most financial sense in terms of owning property - let's get that clear.And as far as sanity goes, I do better when I know my tenants are not trashing the place.

Are they looking for a structural certification of the physical foundation or a document that makes the home a permanent part of the land as opposed to 'personal property'? 

Sounds like your dismissing rent owed, but in the long run if they can agree to it and it can be done legally, it often saves money and significant time in the long run.Forgot to add, Don't physically enter the property at this point.

In short, now that I have recovered more of my time I am physically more healthy, closer with my family, and building longterm wealth rather than trading time for money.   

I eventually found investing in syndicated deals to be the perfect combination of being passive and giving me the benefits of owning physical real estate.

The policy in the lease is that tenants should not make any changes to the property, but I would like the opportunity to make exceptions when it makes sense.I will require this to be done by a bonded and insured contractor, and require them to sign a physical document that outlines the terms and costs involved.

I have visited sites that show me important stats but obviously being physically in the market (or having someone there for you) is best.

Can you bid online or do you physically have to go to the courthouse for these auctions?
