I have an older but in very good shape 2000sf double wide mobile home. 4bed 2bath central air/heat. 

Imagine driving that in the Texas heat?

Develop a relationship with a good realtor that knows the areas well and also utilize the Trulia crime heat map.

I acquired an absolutely beautiful 2 family in Brighton back in February, but I have a bit of a problem...The house has exclusively electric heat. 

The markets have heated up a little too much for my liking though recently.

The product is heat sensitive and hot air accumulates .

The town that the property is in wants a heat loss study done.

Can I deduct the cost of buying air conditioners and fans from rent if my landlord doesn't want to fix our central AC/heat unit?

Now selling the next buyer with 5 to 10 years of ownership can see a wild swing in costs the other way as water heaters, a/c and heating,roof,windows,etc. might need replacing.Buyer should not get caught up in the multifamily bubble we have been having the last 2 to 3 years.
