I'm wondering what am I allowed to do with the 150 square feet besides ingress/egress.For example: Can I add 150 square feet to the structure, including an exterior door, and then use the extra 150 square feet for a kitchenette?

Smaller square footage compared to Whisper as a 4 bedroom, which might limit potential rental income.b) Whisper, San Marcos:Larger home with an extra study room, which is a valuable feature for potential tenants looking for office space.

Depends on state laws and if the broker wants to deal with whatever extra hassles involved.

As such, third parties (lenders, brokers, tenants etc.) should sign contracts with the Management Company and not the Investment Entity to add an extra layer of protection for the Investment Entity against any lawsuits arising from those contracts.

It's layered, which in many ways isn't simple, but it does make it much easier to do my taxes at the end of the year because of this layering.

Local handyman that has an extra set of hands might do it, but it's really a 3 man job for effeciency. 

Regardless, I would highly recommend paying the extra few bucks other insurance companies charge and go with an Insurance provider that gets you what you need when you need it.  

The appreciation and extra income are great benefits, and by holding onto it, you can take advantage of the 2.5% interest rate and $2000/month cash flow while avoiding capital gains taxes.Instead of selling or converting the duplex into condos, consider using your HELOC or a home equity loan to buy or build your new single-family home.

As always, you get what you pay for, and the services of a good Realtor is worth the extra few %.
