God Bless you and your family. Having an apartment there for the 6 months will really confirm that the job is a good fit for you, and give you a feeling for the area....
I am with
@Mini Horses .... I could not imagine a mortgage payment with a comma in the amount... HOLY COW.... I am too old and too set back in the "dark ages" to have a payment like that facing me... OKAY, granted we make the farm payment once a year and it is the equivalent to a little less than 12 months of payments... but we have a cattle check to help pay for the 100 + acres...barns and all... there is no house...but the cattle make the payment....
Still, I cannot imagine a house on 6 acres m/l could cost so much. That's about double what the average one costs around here... of course you get into the fancier ones like the 4 br/ 4 bath one in the picture...the ones like that are expensive here too.
I like the first one, with the pond and all... looks "homey"... the other one is HUGE.... but you do have a growing family........price sure goes along with the size....
Nice thing is they all have barns already there... but then that would be a requirement for you to keep the animals...
At least this gives you guys time to settle into the job, and look around... and get your other place ready to sell like you said...
I'm happy that there are possibilities for you guys...
DH being able to transfer, not job hunt is certainly a plus.....the 6 months interim is gonna be tough. 
I could not buy my farm on today's market! How scary. Salaries are way different than when I was in the normal job market years ago.
And my county gives an elder reduction on RE tx...mine is $2k a year, plus basic rates are good, so that's a plus.
