You have a lot of pieces here...but yes you pay State income tax on the income generated in that State.

Here are some important things to consider:- I am pretty much at capacity running my RE business, so I don't have a ton of bandwidth to do it all myself- Let's presume my opportunity cost is such that pulling away from my RE business to "do it all myself" for these rentals is not a good use of my time, as I'd earn a higher dollar per hour being the CEO of my RE business than the dollars per hour savings trying find off market deals (I.e. saving 20k and trying to do the rentals myself would cost me more than 20k of lost opportunity cost by pulling my attention away from CEO level tasks at my RE business, which might generate 40k of revenue for the same time)- By the same light, turnkey could be an option, I'd be willing to pay the turnkey premium for the time savings of finding and vetting my own deal, however I know I'd still need to underwrite my own deal provided by a TK company, so having someone who can help that underwriting process would be super valuable, rather than me trying to learn from scratch how to properly underwrite the deal.

We have a relationship with Foremost and have been happy with the customer service and claim payout, but they have not been super competetive lately.

I am still learning so until I get better grasp and understanding I want to continue to do the driving for dollars, and generating lists my self, but that doesn't mean that I have to answer the phone during the day from potential leads.I believe the solution to this is to use a phone answering service to take down numbers for me to call back.  

You don't start making the real money till you determine who your core customer is and then turn things up to 1,000 to attract that specific type of customer.

Once you determine your market, its a matter of generating a list of properties and marketing to them in a variety of ways.

Would be awesome to provide a solution for compensation as a result of this project.A Systems Engineer typically designs, improves, and manages systems, which are then followed to develop something (end product) which is then used by customers.

I believe in generational wealth.

I wish I would have custom built a smaller home with the guest house addition!

Eventually, they own 50, 100, or more rental units.BUT...even though I built several homes for customers my brain can't handle looking for lots and then dealing with all the blueprints, dealing with the building departments, contractors and sometimes it takes several years to complete a project from the time you find a lot.
