Several of my mobiles have different rents that were grandfathered in, so that helps, but several are on the same rent and occasionally someone will forget their printed deposit slip and just go to the bank and hand write one out and not put the unit number on. 

I only know of this from a conversation with another landlord of an RSO because my property has no parking at all.Also, if you do separate the parking lease, be very upfront about it and don't make it seem like you are hiding it in the fine print of your advert. 

It is stated on the main lease agreement in print that room rentals are not allowed unless agreed upon by the landlord in writing.

@Jay BarleyAs for driving for dollars, try and print a good map and pregame the area you want to drive around.

Insurance companies, and this includes umbrella policies, will deny or challenge your claim especially if the damage / claim is high and based on negligence or any fault of your's, READ your small print and don't think you are so good at landlording that accidents won't happen.

If you have them printed out, you can reference them next time you take a call to make sure you dont miss any of your questions.

Think about working with a mailing list broker to make some suggestions.Also be sure that the list you get has been run through the National Change of Address (NCOA) so you don't waste printing a postage mailing to bad addresses.

I am not sure artificially holding rates low and printing money is the best plan long term for this country.

It allows people to take cash to a CVS or Ace Cash Express, pay their rent using a QR code on their phone (or we can print one for them) and boom -- payment shows up on their ledgerAccepting cash is a terrible idea. 

Since the 1031 exchange is a federal statute it applies nationally and any good QI with a national foot print can help you out - including me  (may the Bigger Pocket community standard gods forgive me) :)Cash is king and you're in a great position.
