I was one of the fortunate ones that was able to get out of the contract and after all expenses (forfeited deposit, legal fees, holding costs, etc) lost less than $20k.  

These do tend to be more expensive but are also on the table as an option.

Treating loan repayments like a non-negotiable expense while reinvesting property cash flow back into building equity.

Faced with mounting expenses, extended timelines, and diminishing returns, we ultimately decided to sell the property instead of continuing with the BRRRR strategy.The Insurance Mistake:The biggest lesson I learned was that I had the wrong type of insurance.

This will allow you separate business income and expenses from personal income and expenses.Since you plan to house hack your bookkeeping and tax return preparation will be more complicated because a percentage of your home expenses will be personal deductions and some will be business deductions.

Expenses for initial repairs before renting are usually capitalized and depreciated.

I see 3-5 as a fad.Fractional ownership - way to much overhead for these to be profitable. think "timeshare".STR in non traditional markets - running a STR is a business and real estate, boils down to location location location - who would want to go to a conference and stay in a STR vs. the hotel where the conference is at, most businesses pay for this I do not see why.Mixed use with green - this has been going on for years- it will continue but it is also more expensive to build - which means higher costs to use.Not trying to be debbie downer, I have seen these attempted to be done in the past and they really have not been successful.I do really like the BTR model though as I continue to see that as a very good option in the future.
