The people who are born and raised in Denver continue to opine about the affordability, but those who are moving into the city with fresh eyes will gladly take their profit from the coasts and pay all cash, over ask in order to live in (again, my opinion) the best city in the country - diverse economy, great work/life balance, friendly people, city without most of the big city problems, 300 days of sunshine....

Simply bolted onto concrete flooring with no foundation perimeter to address water intrusion issues when it rains.

It seems like it might be best to find that middle 'sweet spot' and go with the median level of finish then in your case (sounds like not wanting to invest a lot to update, and want to keep cash flow at max.)If I were to run comps and see on the high end of area rentals it meant all new countertops, appliances (high end), hard wood/laminate, kitchen cabinets etc and on the low end it meant more of an 'apartment level' finish - I personally would go for the middle road to this and maybe choose to refinish countertops, refinish kitchen cabinets and go strictly mid-range on appliances (I would pick up the extend warranties personally).In hitting the kitchen and baths, getting some fresh paint up and addressing flooring- I would know the heavy 'where the eyes are drawn to' items were checked off my list, take it all for expenses come tax time and be pretty happy to know I was right in the middle zone for the area- I wouldn't have the lowest quality of renter pool in the area, or be worried about overpricing myself out of the competition on the high end in my mind. 

All of them have a lifespan, Roofs, floors, hot water heater, appliances, hvac, bath and kitchen remodel, etc.

Questions:Have your tenants been okay with the staining and slight smells of this water?

You have to use money to give the seller "moving money", money to bring the loan current if they are behind, money for title reports, money for escrow, money for advertising, money for making the payments after you take ownership, money for repairs if needed, money for cleaning the property, money in reserve in case everything falls apart (just to mention the big ones, there are also Insurance, water, electricity, power, property taxes and so on).

Utilities in this area (-electric, water, sewer) are about $100 monthly if occupied. 

Do you know how to spot water damage?

However, since acquiring the property, the taxes went up by 32% and expenses (which I pay) such as electric, gas and water/sewer have increased significantly (perhaps due to COVID).

The first 10 years I didn’t have to repair hardly any furnace/ac units, garage doors and openers, water lines/sewer lines.
