@Victor Yang To use the rental losses to offset any active income (W2), you'd have meet Real Estate Professional status (which would be difficult to do with a W2 job because you'd have to work more on real estate than any other job to qualify) OR have an AGI of $150K or less.

Many carriers are including exclusions for GC commercial general liability coverage and professional liability coverage for engagements involving condos and even stricter exclusions when dealing with conversions.

@Daniel MadhavapallilYou should hire a tax professional. 

However, you can defer taxes under §1033 involuntary conversion if you elect to reinvest the proceeds into a similar rental property within two years (three years if the government condemns the property or threatens to do so, and four years for a principal residence in a federally declared disaster area).To reduce taxable gain, consider:Electing §1033 treatment and reinvesting the full $300K into a new rental property to defer taxes completely.Partial reinvestment, where only the portion not reinvested is taxable.Properly documenting all replacement costs and property details to ensure IRS compliance.Using cost segregation on the new property to accelerate depreciation and offset future taxable income.Since the §1033 election must be made, consult a tax professional to ensure compliance and maximize deferral benefits.This post does not create a CPA-Client relationship.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I am currently looking to Purchase and Rehab a House in the North Dallas and DFW areas.I am eager to Network with fellow Investors and Professionals in the area to explore Opportunities for Collaboration.

Ask lots of questions and you will receive great insight from professionals!

However, the tax treatment differs between short-term and long-term rentals:Short-Term Rentals (STRs): If you materially participate (work 100+ hours and more than anyone else on the property), you may be able to offset rental deductions against W-2 or other active income, offering greater tax benefits.Long-Term Rentals (LTRs): If your AGI exceeds $100K, your rental losses may be limited, unless you qualify as a Real Estate Professional (REPS).If you plan to expand your rental portfolio, consider an LLC later for liability protection and easier management.

My goals are to start building an investment portfolio of professionally managed (I could tell you all the reasons I will not do it myself) multi-family properties and, in time, develop a property in the Northwoods (Wisconsin/UP).

Trying to be professional and courteous.
