I am looking into electronic payment but for now it’s check or Money Order sent USPS.

@Brian Ulrich probably best to claim the correct amount per the Internal Revenue Code - which is the lower of FMV or your adjusted basis.

@Christopher B Leab If you mean electronic forms, look at Google Forms.  

Shelter the homeless, feed the hungry, care for the sick, support our international missions that much more?  

They are great for high end electronics where prices drop quickly.

@Dana R. just because some people had problems with one electronic rent payment company hardly means that all electronic payment is bad.

Venting outside is International Building Code.Buy a roof vent with a flashing shroud, backdraft damper, and flexible duct.

@Ashish Acharya was right on in bring the sources from the Internal Revenue Code. 

@Fabian PerazaNot a fan of self-locking door sets for two reasons: the first, as you mentioned, tenants tend to lock themselves out more frequently; the second is they are generally an inferior quality lock (grade 3 ... maybe) not suitable for en external entrance.With deadbolts and dead latches, you have the option of using electronic locks that will either delay the latch/lock when someone exits (accommodating the ohnosecond ) or enables you to unlock the door remotely (after confirming the tenants identity).

I had this internal debate, or got stuck in sort of an analysis-paralysis mode, for years...until I stumbled across Keith Weinhold’s Get Rich Education (GRE) podcast at the beginning of 2017.Here was someone who, like me, didn’t want to spend time managing tenants and admitted that he was not very handy at all, yet he was financially free after a period of about 15 years of real estate investing and the best part was he did so passively.
