After weighting all of that, does it make the most sense to try to keep this tenant in place? 

How certain of the appreciation are you would also play into that question.Run some scenarios on what you could do with the extra cash vs what you stand to gain from the appreciation play and decide based on that and your goals.

Commissions are generally considered part of the acquisition costs, which are added to the property’s basis (the starting point for calculating depreciation and capital gains).Since you’re planning to rent out the ADU, you could depreciate the ADU's share of the property over time, which may indirectly allow you to benefit from the commission expense.

But it warns you of a connection happening to your account, and that simple prompt is often the last barrier before the attacker gain access to your email or business environment.

As for taxes, they only delay capital gains, not reduce them entirely.

Hi Scott, consider USFR for zero risk cash, earns 5.4% holding 8 week Floating rate note US treasuriesor for mild risk cash, consider BKN - BlackRock's Muni fund, earns 5.6% tax free, which for you would be >9% tax-equivalent yield, and if rates fall, the BKN etf will rise considerably, which though will be capital gains taxable :(, It holds intermediate term Municipals that are all GO, general obligation, so they can always tax us dumb schmuck citizens to pay off the notes instead of defaulting, so low risk but not zero risk for cash. ie (Orange county '90s)Inflation has already resolved, the 3 month trailing core PCE is at 1.5%, well below FEDs 2% target, so they will likely start cutting soon as the 12 month trail falls in line, that's why Powell changed his verbiage so much last Wednesday, and FOMC minutes speak of 150 bp cuts before the end of December as their expectation per their Dot Plots, the only question remaining is consumer spending,(>60% US economy), if falling like McDonalds/Starbucks/Uber saying then unemployment will accelerate and then possible recession, then 10yr yield falls even more, and bonds values would rise like Mike just said above.

And you would now owe about 330k by then so you would have gained 370k in equity in 10 years.  

Thus, you kick any capital gains down the road. 5) The best part of the law says that once it has been an investment for a certain number of years, you can actually move into it, and once you have owned it for a certain number of years, the capital gains you kicked down the road can be rolled into the capital gains that is exempt as your personal residence.

What make it hard to enforce is that the ‘Post Nup” must have both sides receive “fair” value - so what exactly is the spouse without the asset gaining?
