I have many apartments and 2 daycare facilities although none in the same building so that would be right up my alley.If you're fairly new to real estate investing and it's not a great deal, there may be some complexity involved so you may want to pass.

Wanted to share a virtual tour of my first rehab I was involved in!

I can answer the “knock down” portion...I was quoted $10,000 to knock down a 3500 square foot wood-frame house and dispose of the materials.  

There should also be an agreement signed by the seller agreeing to pay any shortage.In other words, this issue should not hold up your closing if you have competent representation and vendors involved.

I just bought a property that is only two units but 6,000 square feet (attic, basement, 2-story barn).

For a 3 BR to be viable you need probably about 1100 to 1200 square feet.

When it comes to adding square footage a permit is technically required even if you are doing some of the work yourself.

What's the cost of new construction per square foot?

I never knew the additional costs involved.

From there, you'll want to talk to folks involved in that bank or business.
