One thing I find no answer is, I am on work visa in US (H1 visa).

It depends on what the sale documents say and how the transaction was made, but generally speaking, you have no privity with the original seller.

My concern is that under the new NAR rules the agreement to hire a buyer's agent obligates the buyer to pay the buyer's agents's commission if the seller refuses to do so, and since the buyer's agent's agreement must be signed before the buyer can view a property or make an offer, the buyer has no guarantee that the seller will agree to pay that commission.

We have previously had a firm no pet policy.  

There's no guarantee that rates will ever return to 3-5%.

No one is skating on this one!!  

Off of the purchase contract, I would verify proof of funds, ask for prequalification letter from a lender if buyer is receiving a loan, with a good faith deposit.

In the ten-year period beginning with Q2 2014, the Downtown submarket has experienced the greatest introduction of new inventory, 19,373 units, amounting to 21.7% of all new market rate rentals added to the market.Asking and Effective RentAfter finishing April with no change, asking rents climbed by 0.3% to $2,381.

The plans I am thinking about would be 100% owned by me to give away at no cost.  

Lots of great insight from the folks above.In my experience as an investor and multifamily lender in the twin cities, I would simply say there is no "right" answer.
