I pay for the lawn care, pest control, Surevestor, actually replace the air filters, and that's the only fee an owner ever pays. 

Check smoke detectors and air filters on HVAC systems.  

You’re asking the right question…I’m active duty Air Force with three rental properties, and I have three VA loans.Sometimes purchasing a home that’s close to turnkey may work if the numbers do. 

However, there's no AC and heat there and I have already purchased min splits air conditioners and an electrician has also laid the lines for me.

For the case of the typical OOS RE investor who would be hiring out work to contractors or using their PM’s maintenance staff for all repairs, I hold my estimate costs and process that derived it is fairly accurate and easier to justify then pulling numbers out of the air. 

Traditionally, DSCR loans that allowed STR have always wanted DSCR to be calculated on long term rental rates OR 12 months of actual performance or some heavily hair cutted version of Air DNA and all of these products would price gauge on rate.

Using your VA loan benefit is another great way to get started in real estate investing.I’m active duty Air Force with four properties.

I've refined and updated my buy box, currently SF detached houses built since year 2000, with 3 bedrooms, 2+ baths, central air, and 2 car garages, in areas with good schools, low crime and economic growth. 

Salt air not so great for machinery.  

Also, air conditioning removes moisture/humidity from the interior airspace, and nearly every home in the Carolinas runs AC during the warm months.Crawlspaces tend to be where the majority of problems occur.
