I would love to connect with local contractors regarding the possibility of building a new construction duplex or a modular home duplex.

If you're going to use the funds to buy another property, I'd recommend doing a cash out refi or possibly a home equity loan (depending on the terms) rather than a HELOC.

Guys, any sites or lists to find an SBA loan broker to help me with the possible purchase of a business?

Scale down your expenses as much as possible.

Now does that mean he was broke, in debt and on life support... no, but it is possible and it started with a relationship on BP.

Is it possible to make money with S8 rentals?

My motivation for a washer and dryer is based on the ease for cleaners to be able to turn the house as easy as possible and I did not even consider what guests would want. 

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

Piggybacking off Peter's number 1 point- get the design team (architect and engineer) engaged as early as possible and let them get construction documents/drawings going as soon as you're sure of the deal going through.

There's also the possibility of becoming the squeaky wheel by calling the police (*not* security) to report the matter.
