Ofcourse I am planning to consult a lawyer first. 

My duplex - built 1989, 2,060 sf, 2 bed/bath, 1 year old roof, value if I subdivide (county already approved) and sell each separately $150k each ($300k total)Investor duplex - built 1995, 2,300 sf, 2 bed/bath, 5 year old roof, value around $310kThe investors initial request was for an equal trade and they would pay realtor fees, which I replied wouldn't be equal due to buying/selling costs (recording fees, title insurance, closing fee, survey, inspections, loan fees, 1031 fees, accountant fees, repairs), taxes would increase due to new sale price, I'd trade a 3.75% mortgage for a higher one, and I'm on the 10th year of a 30 year loan so resetting that to a new loan would restart amortization and pay more towards interest.

E&O insurance, MLS fees, electronic lockbox fees, association dues, contract fees, every software agents use.Many of these fees could be close to doubling by the end of 2026.

Some people will say, "Take out a quality Insurance Policy and you will be protected."

Insurance costs have been crushing cashflow on a lot of rentals as well - I've seen HOI quotes on $200k-300k houses come in as much as $200.00/month over expectations.

Leverage technology early and put everything in the cloud, so you can access info wherever you are.Make sure to get properly licensed and obtain E&O Insurance.

His lawyer even told our lawyer he had a crappy case.I was a bit annoyed that our insurance company settled for a $70K payout. 

-Paying all the taxes, maintenance and insurance-Finding a renter-Worrying and wondering each month if the tenant will pay on time-Fixes/repairs-Other? 

Those can indicate poor management, deferred maintenance, difficult and expensive upkeep like ocean front which will bring up issues with rising oceans, insurance, and hurricanes. 

There is an offer to buy but if I include everything I've spent over the years, mortgage P&I, taxes, insurance, HOA, and recent repairs, I will just break even.
