Had properties with depreciation of 15 years accelerated under Reagan, then 27.5 years after that, so I had properties with depreciation accounts of various lengths over the years.In recent years, on one occasion told me I can charge off items that I was thought I could depreciate, and several years ago, installed new AC's and he charged off 50% the 1st year and the rest over 5 years.

On an occasion or two I've seen friends/family or connections agree to be on lease agreements and take responsibility for the rent payment on paper, while the owner/operator was able to short term rent the property for much more than the rent payment.

And I am in your system and I have spoken with Hard Money on the phone on a couple of occasions. 

My lease also states that "if tenant is late paying on two or more occasions, landlord and landlords option may terminate the lease". 

I met one yesterday where the unlicensed broker took people through the property on several occasions telling the owner they were there to "inspect" the property.

Unless you can remotely reach your router, I might recommend providing physical access to the router for your guests as I have on occasion had them reset it, especially if you're installing Wi-Fi connected locks.  

I have pulled the permits on some occasions, and when using a GC he/she pulls the permits.

And I took one closet and converted it to a private writing space with a granite desktop and custom cabinetry.I also added complimentary coffee and tea, enough for three days.On occasion I offer free tickets to movies, Moody Gardens, restaurant certificates, etc based on length of stay.Little things like that set my property apart from the others and I pretty much stay booked year round.

Does this person just visit on occasion or do they sleep there regularly.

I've disclosed on many occasions, I, and most investors I know, frequently purchase properties with no earnest money involved.
