Congrats on a great investment. Arvada is only becoming more popular. Based on what we're seeing in Denver right now (~3 weeks of inventory, median <6 days on market), I expect 2021 to be another hot year for real estate.
People continue to move to Colorado. US News ranks 4 of the top 5 best places to live in the US in Colorado! And, the Denver Metro Area has appreciated 49 of the past 50 years, with an average around 6% while the national average is 3%. Past performance is no predictor of future results, but historical and present data suggests you can count on future appreciation.
A lot of people are wondering about a looming foreclosure crisis, but the data does not suggest that happening.
Approximately 8% (90,366) of homes in Colorado are in forbearance. Of those 90,366 homes, only 5% (or 4,518) are delinquent. This means 0.27% of all homes in Colorado are delinquent. Even if all those homes came on the market at the same time, it would only add another 2-3 weeks of inventory.
Based on all this market data, I don't expect a crash and if anything, the future looks stable for real estate. Of course, I don't have a crystal ball.
More importantly, I would consider your present situation, for the good reasons @Greg Scott points out: 1) You want your equity working for you. You have quite a bit of equity sitting idle in your house. 2) Appreciation is speculative and only capitalized when you sell/refinance. You have a great opportunity to do that given the reality of today's financial and real estate markets.
Given the current interest rates and strong market, you have two great options:
1) 1031 (sell and avoid capital gains tax if the $ is reinvested) your property into another investment, possibly with more doors that cash-flows at a higher margin
2) Refinance and pull out $ through a HELOC for a downpayment on another investment property.
It's worth emphasizing the opportunity of the present moment: Interest rates are at historical lows. Even though prices are higher, what you can actually afford may be greater. Such dramatically low interest rates lead to significantly smaller monthly mortgage payments.
