If you need to discuss this in detail send me a message or reach out.

*I am providing these details because the question of our abilities as landlords has been raised. 

Or you could find a group with a 30 year fixed (or Adjustable Rate) with reduced or removed Prepayment Penalty, but they will usually charge extra points or a higher rate to do it.Not 100% sure on the strategy behind it, but would be happy to connect and talk through either.Good luck!

It's extra work, with no benefit to you...and possible issues going forward with more expense to replace and a movement away from anything gas, particularly in blue states. 

idk, i feel like there are necessary details missing here. but i'm also wondering if it would make sense to just reallocate the percentages based on what each person is bringing to the table. it would've been easier if you did have an LLC whose operating agreement you could just change. there's also the 'lazy' 1031 or 'reverse' 1031 where you just make the sale, then strategize with your cpa on how to offset the cap gains for that year. also worth noting: 1/3 of something is better than all of nothing. it sounds like it's not really that partnerships aren't working, it's moreso that you feel like your % is no longer fair? 

Make sure you have documentation of your own - Get a licensed Contractor (not a handyman) in there to give you a detailed bid.

Cost of construction is high and you may be paying extra to match 2024 building codes rather than a remodel/addition.

Thanks for these details!

Because I was underwater, and had the income to support paying the extra, I kept the property.

There are closing costs, loan origination fees and Homeowner's Insurance to add into the number, You will get better detail from whomever is lending the money.
