-Christopher I agree with having a lease that spells out everything, and I've seen people recommend language in a lease that puts the charge on the tenant under $X.I don't personally like or use this clause, because I feel the tenants will not tell me about small things that have the potential to become huge things, like a dripping pipe.

Add alerts for the niches and markets you're interested in, but don't forget alternate spellings or abbreviations (so, for example, "turnkey" "turn-key" "TK" "turn key", or "Alabama" "Birmingham, AL" "Birmingham, Alabama"  maybe even "BHAM").

Many students are shown on TV as spell bees and high school grads mostly attend four year universities.

Make sure you set up your alerts well, including different spellings and abbreviations to ensure you cast a wide net (so "SFR" as well as "single family rental", for example). 

as for the "30 day out", clause on leases...I would think you could have this as long as each infraction is spelled out.....vulgar language to PM or representative, cleanliness, excessive complaints after signing an "as is" acceptance of property, loud activities resulting in no less than 1 complaint....the list could go on until you could give a thirty day notice for a hostile stare.  

This has nothing to do with your proposal, unless I am missing something......you will have a contract spelling out the term and interest rate, with or without a balloon, then execute a note and mortgage with those terms.

They either move out or continue to rent.The non refundable deposit and the extra rent payments are kept by the landlord if the tenant decides not to exercise the option.Seller financing is just the owner extending financing using a promissory note to the buyer, spelling out down payment,  interest rate, repayment schedule, balloon payment, consequences of default, closing costs, and servicing fees.

If you mean an actual one time additional "assessment" for large renovations, then it will be spelled out.

Just make sure you completely spell out your intentions before you sign anything.
