Seriously, once you've seen the light of syndications, 1031s seem like a puzzle with too many pieces.If you're ever stuck or just want to swap stories, give me a shout.

I would also mention the hot water radiators keep the heat longer vs forced air.There's a lot to contend with assuming OP has a boiler now and only wants to swap out a boiler without disturbing the radiators and supply lines currently.Now if we are talking blank slate I would do forced air all day long as its cheaper for the unit and running the duct work.

THAT's why market minimum mean nothing but opportunity to be the PREFERED units, what better tenants mean, and how to think like a business owner than a swap-meet trader. 

Once we get 9 years on the SUV we will swap it out with a truck.

It will increase cash flow, reduce leverage, and the only downside is that the total asset value would be 50% lower, so I would get appreciation only on $150,000 and not on $300,000, but overall in the grand scheme of things I think it makes more sense, rather than scraping $100 a month but feel like you're fully optimized and every penny allocated according to the spreadsheet.I also realize everyone's risk tolerance and situation is different, if I have to sum it up this situation to me feels like a no brainer because numbers wise (trust me I ran the numbers) - cash flow would remain the same (assuming I went on with cashing out and buying more) but with lower debt so more room for error, and where I am "missing out" is debt paydown which again, with these rates is really insignificant, and appreciation on a higher total amount of assets, which I'm happy to give up on for the time being and swap it for greater peace of mind.What are your thoughts?

I can swap out an element and upper limit t-stat in minutes. 

Logistically, the "swapping out" is pretty straightforward since almost everything is the same as a AirBNB. 

I would love to swap stories and see how we can help each other.

Happy to swap data from my STR in NC if you're looking to diversify markets and wanted some info.

One of them is drop and swaps.
