This does not mean you can leave the unit vacant for 6 months (not that I'm accusing you of wanting that) but it also does not mean you can be forced to accept a less desirable tenant nor can you be forced to lower your rent.

If someone had an "event" in their life (illness, divorce, etc) then we may be willing to accept that, but if someone has had their vehicle repoed, they have items in collections, and a history of late payments, we'll pass.

However, $1K is much higher than what we pay.We do not allow partial payments and I find it curious that your PM accepted that.  

You never know who will apply, and you are not obligated to accept them.

However, this price is much lower than the listing, and the seller is unlikely to accept it.

I just accepted your friend request and followed you bac 🙂

While I never before or since accepted any like offer, the amount I was paid for minimal time was too good to pass up.

I would like to have a loan calculator in order to do offers with out using mortgage broker before have accepted offer.

Credit score is acceptable, he has no evictions, have enough income to cover rent comfortable. but then i am here as it's useful to learn from others experience for this kind of profile and background that I have no experience with.   

A concession is primarily for the buyer(s) benefit, it can help seller(s) to sell a property but there is really no advantage to a seller accepting an offer with a concession except that it is incentive for the buyer(s) to focus on that property, it makes the terms more attractive.
