Keep in mind that you get to depreciate these appliances on your taxes.

This benefit allows the owner’s estate or heirs to receive the property at a new, higher basis—reducing capital gains taxes if they choose to sell the property after inheriting it.In short, partial disposition allows tax deductions for retired property components during ownership, while the death step-up basis resets the property’s depreciated value, providing tax relief for heirs.

With enough knowledge you can make a educated decision on which approach you take.My experience:I personally don't sign up for any program who take you aside during events and try to sell packages that is just blatant sales strategy.Once you sign up there is every attempt to make you sign for their programs for bookkeeping, registered agent, LLC or corp setup fee which have ridiculous even with platinum membership.Basic standard structure they suggest to take advantage of multiple deductions can be easily achieved by proper education or work with a good firm like https://wcginc.com  who is local to you.A umbrella C-crop to manage all other LLC properties and take advantage of many tax deductions that are not available with a llc, its also used to take losses up to 100K as startup expenses and dissolve the entity after few years.Few LLC entities for investing in Real Estate, etc preferably in Wyoming or Nevada ( you can find many companies online who can do this for $150 compared to anderson $1500-$3000) , they will claim they have a secret Operating agreement which is bogus.They certainly try to take advantage of tax loopholes and claim to be smart people, my view they are just taking advantage of numbers as per their own statements.

They lowered the “taxable value” by 40-50% and then raised the tax rate about 35-45% lowering everyone’s taxes that year.

It’s definitely smart to evaluate the tax and cost implications of your funding options.

Quote from @Joshua Tucker: What specific tax benefits can high net worth individuals receive from building real estate on tribal land?

if it is unsecured loan that is the consequence, you lose they entire thing. as far as tax write off, sorry but none.

It scales up to 37% once you get to around $12k of income but the UBIT is calculated after the first $1000 is deducted along with expenses and depreciation again only on the same % the property is mortgaged.

I mainly want to ask if these assumptions are reasonable and if there's anything I haven't considered:(1) multifamily units in NJ close to New York City, ~$1,000,000, 20% down payment, (2) Using the following assumptions: 4% appreciation rate, 6.5% interest rate and 5.0% refinance after 5 years, $10,000 yearly maintenance fee(3) ~$6,000 monthly rental and assume 3% increase yearly with 5% vacancy rate(4) Based on the above, the calculated IRR if selling at the 10th year is ~19% (considering tax benefits) and ~17% (without tax benefits).

This might make sense, but again, you are just deferring the taxes and now pushing tax from capital gains to ordinary income.
