For instance cashing out 280k from my primary residence and use it as down payment to purchase a 700k investment property.Thanks,Jason

Another investor will see the value differently than someone occupying it as a primary residence, but it still carries value in both cases.

What would be the best solution for my future properties?

If I were a resident I would like the somewhat isolated location of the town but it seems far from many major employers, that is unless your tenant works at one of the many warehouses nearby. 

When you refinance a property, it's already in service, thus no adjustment to depreciation.Special rules apply to primary residences converted to rentals.You should understand how refinancing a property will limit your ability to write off the interest.

So for an individual, it would be something like "John Doe, an adult, who resides at _______________________" For LLCs, it would look like "Blah LLC, a _____________ (State of Incorporation) Limited Liability Company, with a registered office at _______________". 

Obviously if you're looking for your own primary residence and you want to live in an upscale neighborhood, sure, pick Summerlin, Henderson, or Southern Highlands.  

The tenant has not signed a lease with me.my mortgage list this property as my primary residence. question: if I offer a month to month term and the tenant agrees, would this supersede the prior agreement with the previous owner?

I live in the great real estate market of Connecticut and thus, became an accidental landlord when my primary residence (2Bd/1Ba) failed to sell.

I've asked around and even my attorney doesn't have a great solution.
