Like I said I have the buyer ready to buy. 

As mentioned above, have good comps.Take a look at the S8 list of available properties so you have an idea of what your prospects are coming from.

@Andrew Albritton Yes, a 1031 exchange is possible, but since your in-laws are related parties, both you (the buyer) and they (the sellers) must hold onto the exchanged properties for at least two years to comply with IRS rules.

Every buyer wants some way to determine if they are being offered a fair deal.

@Craig Holland Land is often sold with owner financing, in part because buyers have a hard time financing it, and in part because buyers often only need a short time before they can build on the land and refinance out of the seller loan. 

I have a deal right now and I need buyers.

Oversimplifying it just a bit, the investor profits from:- a non-refundable option paid by the tenant-buyer which gives them the right to purchase the property within their option period- the spread between the rent paid by the investor to the property owner and the rent paid to the investor by the tenant-buyer over the life of the option- the spread between the price ultimately paid by the investor when they exercise their option with the owner and the price ultimately paid by the tenant-buyer when they exercise their option with the investorClear as mud?

Now with the NAR settlement, all buyer commissions are negotiable in the contract. 

They find properties and approach Sellers and secure a price, then they seek out an end Buyer (you) and sell it to you at a higher price. 

So it's very easy to criticize these markets if you've never been here or really know anything about the area and are just making broad, sweeping generalizations, but if you have a strong team on the ground who can help you buy in the right neighborhoods and maximize your returns, you can do very well in this market, and I'm sure Detroit as well.I had a buyer who bought a duplex in Cleveland for 85k last year.
