Should i be asking for lower tham 550k to have a greater built in under market cushion?

Imagine the same scenario with a duplex that was built that way from initial construction. 

Purchase price: $80,000 Cash invested: $65,000 Re-built my families flooring company and it started with this building!

Hell, I've got an offer out right now on a place that was built in 1897.

I would say that the best scenario would be to buy something that is already built out and permitted with some type of ADU or mother-in-law.

It has a finished attic that is not one of the BRs and do not believe the finished attic would meet today's construction code (the property was built in the 40s/50s). 

Now I can just pick up the phone as I have built out many solid relationships with very knowledgeable investors.

I thought the same thing until I realized that NNN won't have the same appreciation that multifamily does since the rental rates won't compound the same unless there are annual rent increases built in instead of 5 year increases!

He ended up having to sell the property to a builder who tore the duplex down and built a new construction house. 

It is an older home built around the early 1900s so everything is all natural wood.
