I currently have a CPA (only handles taxes and offers standard tax deductions advice) and a wealth manager at Abacus (handles retirement investments and stocks- IRA, 401K, etc).

After two years we moved into our own house and continued to rent it out.

It's in a well sought after neighborhood with good schools that I remodeled to appeal to modern tastes.

Is anyone else interested in starting a mastermind? I've recently been inspired by Pace Morby. I think the mastermind would be a great way to keep accountability in taking action on creative finance deals.

If we purchases a home as an investment property, build a DADU, and sell the home and DADU (around 12 months after the purchase), what's the best strategy for tax saving?

Basically get that 30-year mortgage after closing

I work with a significant number of hotel entities, I can address this from a tax perspective, I'll leave the liability issues to the attorneys.The lessee / lessor entity structure can be used for a few different tax reasons:1) There is a REIT investor - in which case they can only have "Rental" type income, while hotel operations generates "Ordinary" income. 

I can pull out about $50k in equity,  but I would not be able to do anything else after getting the place.

I am thinking of a system where my investor-based agent gives me a ball park, and after that I pay contractors to go in and give me itemized bids, what do you think about that?

Personally, I think the taxes are high and the services you get for your taxes low there.I know people that invest in Detroit but you must know the area down to the street and have excellent property management.However, I just talked to my CPA today about a referral he was sending me who is a client of his that has 30 rental properties in Detroit and selling them all because the City doesn't really help, charges for everything, and they never have given a security deposit back to a tenant after they stayed because of their behavior or lack of payment.
