@Ahmed SaadAhmed made excellent points and I agree with everything he said..You need to know your market you’re in a very Tenant friendly market consider yourselve lucky I have many landlord friends in NYC that their tenants are having difficulties paying rent due to Covid and stimulus drying up and they can’t do much about it your issue is easy to resolve vs a tenant unable to pay rent.

How much appreciation you think is left, in my case I decided the biggest appreciation is like behind it, and honestly and this is a personal question but your goals and overall financial picture and risk profile, in my case I felt making 120k in two years was fantastic and I’d like to take the win, I figure I’d keep my powder dry in case something else comes up, I figured I could still make a decent return in the stock/bond market.

In many areas, the soil in Colorado is heavy clay.

If you want to really get the details, here is the place to start.On expansive soil, there is some in Las Vegas but it is in a relatively small area.

I'm a land investor and typically I buy and sell vacant land to retail buyers, sometimes work directly with home builders, but I'm wondering if we get into a recession type economy if those two buyers will dry up, and if I should pivot to looking to work with land bankers or people who are interested in land banking.  

Worst case for me is that the money I dump on it is making me 4.2% (actually a better return than a lot of landlords these days) by saving me 4.2% on my heloc interest expense while I wait.It leaves me with dry powder when the next buying opportunity comes around and since the draw period is 10 years I'm feeling pretty confident that I'll have plenty of dry power ready when the market turns.And in the meantime it allows me to accelerate once again into a free and clear primary barring any unfortunate "too good to pass up" deal that I'll need to ply my wife with flowers  and maybe a little convertible to get her to say yes to.Kind of like a real savings account that's paying me 4.2% while i decide where to use it.  

Besides safety, the maintenance and life of the deck and stairs are compromised because of items sitting on the wood not letting it dry properly and restricting the ability to clean and maintain it.There shall be no use of grills on the wooden deck because it can cause a fire hazard and can damage the wood with grease or ash.

All that to say don't trust an agent, most are gone before the ink dries.

If they leave you high and dry and move out in a week, can you afford to cover the mortgage?

It's going to take a lot of competent sanding and polyurethane application and drying time to get it done.
