What will your combined W2 income be after taxes when you get married?

We are a growing family and need more space and of course, more opportunity for income building. 

I stumbled on some information about short term rental tax benefits as it pertains to lowering W-2 Income. 

Not to mention I got to write off over $175k from my income taxes using a cost-segregation study.  

There actually is this weird scenario, just past goldilocks, and closer to Alice in Wonderland, where the economy keeps chugging along…. slowly, household incomes crawl ahead, corporate earnings play duck duck goose, unemployment (usually) rises and inflation stagnates.

Or the other likely problem - negative cash flow (the income projections aren't addressed here, and it seems highly likely based on the financing.)  

Net Operating Income / Property Cost = Capitalization Rate

What if it sits vacant for a month, and you lose the entire $3,500 rent income plus the cost of utilities, lawn mowing, and other expenses?

If you need to build reserves after acquiring the property, allocating a portion of the rent towards reserves is essential, aiming for at least 10-15% of the gross monthly rent until you reach a comfortable level, ideally 3-6 months of rental income.

I'm curious on how best to structure this approach: Who owns what, who gets what, rental income & depreciation (all tax treatment).
