Btw, your website is very cool and modern@Leo B.

When a NNN lease is combined with a single national credit tenant, the investor can be assured of a management free property with minimal risk.

It wasn't cool exactly, and in the modern age I guess you couldn't say weird anymore either.  

I think it was a combination of both spending too much for Contractor and level of materials.  

A modern, direct-vented, condensing hot-water heater will have an annual fuel utilization efficiency (AFUE) rating  >90.   

This could be a separate unit by itself but we're told it makes more sense to combine w/ 1st floor unit and create a duplex- Don't know complete layout of property but have been told that 2nd and 3rd are already a unit (a large one).  

(good Debt)  You will have a wicked combination for wealth Generation.  

Try to find a bank to do a small portfolio commercial grade loan (5 units combined) for an equity out refinance.Pro's: - Potentially the highest loan dollars due to a commercial loan basing the LTV off NOICon's:- Probably the highest interest rate due to small commercial loan (current loan interest on the properties is at 3.25%- 3.5%); difficulty in finding a willing lender; generally non-self amortizing terms meaning I have to refinance in 5 or 10 years; higher closing costs; couples the properties together, makes exit strategies a little more limited2.

So be careful there.Reasonably modern purpose-built fourplexes like you see in much of the country are very rare.  

Most people practice modern portfolio theory, it's what I was taught when I studied Finance in college.
