For at least half of nearly forty years life I've lived and invested in property within a block or short walk to the beach in South Florida, Southern California, Southern Oregon and Northern Baja Mexico. 

While they seemed nice enough during the walk throughs, I could sense that they were not going to be particularly happy to have a new landlord coming into the picture and kicking one of them out.  

We did a walk through and did not smell anything 2 days ago. so afterthe complaint we said we could go there and inspect.tenant started getting really angry and complaining about other things and how much rent they pay and we are greedy.

It's usually around $15 on Amazon. https://amzn.to/3VKVLLP He virtually walks you through this step by step, and it's a great resource if you have questions later and don't want to go back to the forums.Second, as a Realtor and investor in Illinois, I agree with everyone.

I had walked the property and told him he was crazy for not making an offer.

They tend to target apartments in walking distance of their single family home via flyers and craigslist.

Always happy to walk through a scenario with you or chat about my situation! 

The only criticism I've heard is that he does not take walk-ins.With advent of technology, locality is optional. 

After a couple of times having people still walk away, I now require that plus a signed lease.

I'll try to give you some feedback in the order you asked it.1) We require a walk through inspection every 6 months for all of our LTRs.
