I agree with all of the fixes being cheap and easy (except for potentially the moisture), but am I the only one confused by this:"- No air filter and nowhere to place one on HVAC"What does this mean? 

Now the driveway and parking lot were already there so no cost for build out and we could use one more load of the gravel come spring so probably another $500.

Property is well kept; Added refrigerated air replacing the swam cooling system that was there when I purchased it.

Then look through those and see what you'd get the most money for if you sold (in the spring because winter is not the time to sell).Rents should go up every year.

I use my CC get my cash rewards/ air miles run them up during projects to conserve cash incase I find the next deal.

As for the lawn, spring has just started and everyone is just doing their first mow so it’s not like we’re behind.

Take into account: bedroom and bathroom counts, square footage of the unit, whether parking is included, whether laundry in in-unit or not or nonexistent, central air vs. window units vs. nothing, and the general condition and age of the interior.Good luck!

The comparable on Air BnB are few, but seem to be renting around $65-85/night.

For MTRs I do not use air bnb. so no I have not.

You've got plenty of time to get creative with your investments, but my biggest advice for our first-timers in Denver and Colorado Springs is to not overthink it.
