Instead the landlord may proceed immediately to end the agreement or make the repair and bill the tenant.I've hired contractors and made the repair.

Here is a link to a 1 page purchase agreement that you can also do "assignments" from as well.

Most banks that sell short sales will require you (and your agent) to sign an affidavit that states you have no other agreements on the property other than your purchase agreement. 

Both of these are prohibited in my lease agreement.

Apparently that's the usual practice around here.I gleaned as much as I could from the proforma, but you shouldn't take the info on it as accurate.Depending on the purchase & sale agreement your agent uses, it should ask for those documents for you to be able to inspect. 

@Issa RicePrivate lenders are people you personally know: friends and family and it's whatever you two come in agreement regarding the down payment.If you're short on the down payment, look into an FHA loan which is 3.5% down, as long as you'll occupy the place.  

@Shawn ConnorsIt depends on the seller and the type of listing agreement.

In such cases, you may not be able to evict but will need to foreclose and that means a judicial foreclosure as you don't have a security agreement with a lease option. 

I would definitely look through the purchase agreement though because it truthfully should have been addressed there.

If you'd like you can PM me on specifics which can lead to a phone call, much easier.BTW, my comment above concerning predatory was not meant to say you were being predatory, but that those acts as seen in that light, When you take something away from a buyer, a "right" or acceptable practice by agreement there needs to be some other aspect that balances out the fairness as consideration for that loss, an additional benefit shown for the buyer.
