I am actually located in the Mt.

And you use the 1031 exchanges for these and buy more "flip" candidate properties.I've actually had clients who built up to 20-30 exchanges a year doing flips and value adds. 

So there are a few ways to look at this, the 1st question is are you sure your renovation’s will double the property value, most renovations on primary residences, your lucky to get 60-70% of the dollar cost back out upon sale, so really nail down your comps, than you have basically a math problem if your rate on your primary goes up how long if ever before that extra payment is more than 400k in taxes, that’s just a simple calculation to help you decide, but I suspect you actually have a different question here, from a purely financial perspective my guess is the best option is to do anything to avoid that tax hit, but one of the reasons to make money is to spend it on things that you enjoy, based on your overall financial picture and a subjective view of how much enjoyment you will get out of a renovated home, you should decide if you want to roll your profit into another deal or “cash-out” your winnings, I love cars and I’m willing to spend more than is fiscally smart on them because they bring me joy, there is nothing wrong with that, but i don’t think it’s a fiscally smart choice, without knowing your exact property id imagine a renovation would fall into that category, so that’s the terms I would use to decide.

If they come out against my favor, can I coax the board HOA to at least talk to the actual attorneys who are experts in condominium law?

Do you actually know if or from whom else he’s borrowing?

I actually think the system could work but they're asking for a lot of $

A full family of rats had actually moved in, taking refuge in the cupboards that were still stocked with old food.Has any other landlord here ever had to deal with a renovation like this?

Anwar actually did it by renting out the room.

Rates will decrease on ALL loans once rates actually decrease in general. 

that's the best way to get started.investing in properties directly is actually not all that passive.
