Never ever ever ever again. ever.When they want something from you, they demand immediate action (Ex: Calling at 10pm to tell me my tenants had put a small yard gnome in the flower bed outside their door, demanding its immediate removal.)But when i requested that the dry rotted outer door jambs be replaced (per by-laws stating they are responsible for "from the studs, out") It took nearly 6 months of emails, phone calls, threatening legal action, and finally petitioning to have the president of the HOA removed.

I've heard of folks requesting/requiring a lock box on a wholesale property; however, I personally would never ask that of a seller as i would never want the keys to my house hanging on the doorknob outside!  

Things will break while someone is there and a poor response to their request can reduce the amount of people wanting to rent there.

These homes have been going for a song. 

James McMurtry wrote about these guys in a song - "Uncle Slayton's got his Texan pride, Back in the thickets with his Asian bride, He's cut that corner pasture into acre lots', He sells 'em owner financed, Strictly to them that's got no kind of credit 'Cause he knows they're slackers, When they miss that payment, Then he takes it back"

To apply it to your question, Appfolio tracks property and tenant information, while allowing tenants, vendors, and owners to create portals for online payments, maintenance requests and tracking, and document sharing.

I have the rent roll, and I am requesting the operating expenses :Property Taxes (I already got this from the county)Insurance (I am getting a quote)Matanance and repair LandscapingGarbage Power (If paid by owner)Water and sewer (If paid by owner)A copy of all leases of all occupied unitsYear the roof was replacedYear when last update took place The age of the AC unitsWhat am I missing? 

Every time you apply for a conventional mortgage you will have to provide the same information on taxes, banks statements, outstanding debts, AND they will pull your credit with each request.  

In a respectful and sophisticated world the tenant should kindly request and notify the landlord of anything that violates a habitability standard in the property and hopefully the landlord will oblige.

Put my commission in the contractCouldn't I , as an unlicensed person, just request the seller to lower the purchase price by 3% (or whatever)?
