I have been investing in real estate as an active duty service member since 2003 and never had any issue having my clearance reviewed or upgraded.

If this is, or if you have not been doing this with your brother for a long time the splits, or breakdown should be broken up however you both see it being far. 

@Matt Lefebvre I am dealing with a situation now where the town fire inspector is mandating 6 fire doors be upgraded in a building that was constructed in 1984.

This is because the IRS assumes that when you use the building (as a rental) a portion of that building will get used up "consumed"; such that after some time you will have to repair / upgrade / rebuild.

I would also do my own research into a likely market price.If I buy it, they'll save broker's commission, plus cost of minor repairs/ upgrading and carrying it while it would have been on the market, which probably amounts to 6 - 7 percent of the purchase price. 

Tell her they are broken and you are replacing them with coin op machines which should work much better.

Upgrade the house until it meets code.

This probably the nicest duplex I've ran across in my market mainly because its newer, has nice upgrades, great floor plan, well built, and its in a great town.

He has approached me to do a electrical service upgrade on a 2 family in unionville and a 4 family in canton.

If however, comparable sales in the area tell you you can sell it for 145k with 20k in upgrades then Maybe 70k is a great deal!
