If I pay the $6000, will that amount be deductible for capital gains tax purposes?

For example, if I were to sell a property and net $50,000 profit, could I elect to exchange $40K of the proceeds towards a new purchase, pay short-term cap gains on $10K and keep the balance? 

I've gained a tremendous amount of loyalty by just going in and making a couple of basic upgrades to set a good first impression with inherited tenants.

As a personal residence where you can build some equity, gain land lording experience, and live a little less expensively...sure, if you like the place.

For some investors, they have a lot of time to do BRRR take the risk and try to gain the rewards. 

The problem is that the property is in too bad of condition to get the upfront, cash price that they're looking to gain. 

When you renew the lease, include an addendum that states any problems must be brought to your attention immediately and in writing. 

Is this a deduction from your capital gains under certain circumstances?

My plan is to gain some capital and build from there. 

The outcome was a positive cash gain, longterm connections/friendships, and inspiration to move the next deal.
