For example, on what I thought was a relatively simple project in a bathroom reno which was fully gutted down to the studs already, I had more than one quote for over $7k to run pex supply lines and rough in a shower drain and toilet drain off of an existing main stack, all of which ended up costing me about $200 in pex lines, PVC fittings, and sawzall blades.If you need any hardwood flooring repaired, patched, or refinished, you can't beat Dave's Hardwood Flooring out of Blaine - $3k spent with them fully brought one of my duplex unit's original 100+ year old maple floors back to life.If you're putting in any stone counters in your kitchens or for bathroom vanities, Twin City Discount Granite have been awesome to work with, and consistently have the best pricing I've found in the area on fully installed granite and quartz.I also have a great drywall guy, as well as a really good carpet install guy - feel free to DM me if you want either of their contact info!

Hey Brother, We've run our cabin in Pigeon forge for 3 years, consistent $90-100K gross rev.

It's tough to see your property sit vacant, especially when you've invested in renovations and are pricing it competitively.I feel you should re-evaluate your management company,If they're consistently pushing for lower rents without providing clear reasons or alternative strategies, it might be worth considering a change.

They apparently do not have time to verify permits (under what criteria units were added or that the work was even done with a permit).To the OP, I fear your property will consistently appraise low when obtaining HELOC or refinancing and that a re-appraisal will not reflect what you are seeing of homes being appraised with an agreed upon negotiated selling price.I am not saying this is the way it should work. 

Become great at systems and processes because that is really the only thing that makes investing work consistently.  

Do you have enough time in these that you can show consistent trends in expenses and vacancy rates?
