This is super cool because it lets me be more hands on and save costs while having an experienced builder helping plug in all the pieces. 

:)Let me first assure y'all that this back-and-forth between Sean and me is in good nature and friendly.

I hope you're all doing well.

Not interested in doing a 1031 exchange.With regards to taxes, what are the advantages / disadvantages of selling all of my rentals in 2025 versus one or two at a time per year. 

You may pay a bit more and make a little less, but playing the long term game is key in real estate.The types of structures could be lump sum (one price) or cost plus (meaning you pay the cost of material and labor plus a flat fee—more of an open-book model).I see some investors who want to pay for ALL the materials, which is excellent for the investor (more control of finishes & cost) and general contractor (if they are getting paid well).  

Numbers and landlord laws didn't make sense at all.

I would do the same thing all over again. 

You asked about a property you have listed for sale and property taxes that are coming due and the consequences of not paying them until the property sells.Generally, the local taxing authority will impose an interest penalty on any unpaid balance after the due date with a long grace period before you would have to worry about unpaid property taxes affecting your ownership of the property or your ability to sell.In all likelihood, the property taxes will become a part of the closing and will be deducted from your proceeds at the time of sale.By the way, property taxes are always in first lien position ahead of any other debts like mortgages.

After all contractor work is done in 10-12 months would than want to rent it out.Thanks 

Quote from @Branden Rivero: The issue I see is the building is close to 100 years old and with a $500 hoa it's not an easy sale for an investor Yes, thats true however all expenses the past year increase insurance, sewer, trash, electric and cleaning service.
