The disadvantages in my opinion are the meeting and greeting and cleaning up after people. there is more management involved and what would happen to your profits if you hired the duty out? 

You do need to be REP or have STR to use the losses from rentals to save your taxes.Since you started renting your single-family home in 2021 and just bought a duplex in 2024, you can use depreciation to reduce your taxable income.

You will need to contact the city Building Dept to ask if there are any city coded you must follow.Or, hire a qualified Property Management Company.

I feel like hiring an attorney will be way more easier because they have the experience.

BDs and Registered Reps are also registered with FINRA and must act as a fiduciary to their clients.

Actually, I don't think anyone here is hiring in your field.

Let me explain with example:- Assume I purchase land worth 50K in August 2024, and then hire contractor/architect and spend over 100+ hours discussing the building plans, etc to either construct a SFR home or a Manufactured/Mobile home.- I will also supervise the construction and other related activities (but will NOT build the house myself) .- Let's assume the total cost of construction is 200K (or 150K if it's a manufactured/mobile home).My Question would thus be- Can the STR tax loophole strategy allow me to offset 60% of the 200K amount that I paid towards construction of the home, (or 60% of 150K if it's a Manufactured home)Any success stories with this kind of approach?  

Don't miss out on the tax-saving opportunities you have from property using this with a REPS or STR strategy.On the other hand, paying cash for a couple of mobile homes is a more straightforward option.

Do you hire an accountant to file your taxes?

Here is what you get when you hire a GC, someone who wants to call subs and add 2 - 3k on top and then never show up at the house, never manage the quality of work from the Subs, do not manage their time.
