I'd use that portion to buy a new primary residence condo (up north). 

No financing cost on the “BR” portion of BRRRR.

.- Since the farmer sibling lives very close to the land and farms it himself, any portion he owns is considered an agricultural investment and property taxes are ~1/2 the normal cost of property taxes.My thoughts:Allocate a portion of the land to each sibling and dissolve the TrustEach sibling can 1031 the land into a desirable rental property near where they live (if they want to)At some point in the future (5-10 years?)

I’d be tempted to try and design an attractive feature on that exterior portion.

We turned live in the mother in law unit and rent out the 3 bed 2 bath portion.

And of course very market specific.But when you look at lower value assets lets say any home that can be purchase for 100k and under which is a great portion of the rental stock in the mid west.. most of those renters pay 700 to 1000 for the house and if they bought them their all in payments would be less than rent and by a lot in many cases.. yet they still don't buy.. 

We close next week & I'll be receiving a nice little portion of the profit from less than an hours worth of work.

Leave yourself enough wiggle room finance wise that if you only sell a portion of those SFs in a good cluster you use only those to purchase your MF. 

Ask the seller to cover a portion. 

Any left over amount Uncle Sam and your state governor will help you by investing a portion in pothole repair lunch breaks, subsidizing the care of dogs owned by the homeless and conducting study to establish if a study is needed to study the effect late night/early morning traffic has on marsupial wildlife living near the freeway.
