An approach you might want to take, is to break down each component of the rehab into its own price per sqft/linear foot/units for both materials and for labor.for example you might find that flooring costs and average of $3.50/sqft labor to install + $3.00/sqft for materials X square feet = cost to refloor+ always add an extra 10% for unforseensSo you would just need to do this for every part of the rehab based on what needs to be done and what level of finish you are going for.keep in mind that some things are measured by sqft, like floor, and others are measured by linear foot, like trim, and some are measured by total area, like drywall and paint, and yet others are measured per each like tubs and toilets.A good place to start with figuring costs is The Book On Estimating Rehab Costs by J.

For newly constructed, purchased or renovated properties and also retroactive generally over the last 10 years, building components are properly classified into individual units of property and accurate recovery periods for computing depreciation deductions.

Bonus depreciation could be a viable strategy to offset your $300K capital gains, but it typically applies to specific property components identified through a cost segregation study rather than the entire residential property itself.

This cpa/real estate podcast has quite a bit of info on all the STR tax components https://podcasts.apple.com/us/podcast/tax-smart-real-estate-...

I hear of all these great profits that are being made investing in real estate that has a major “business” component, like small assisted living properties; rooming houses; sober living arrangements, etc.  

Facebook and social media can have lots of local groups that you can put your Questions to locals "what does this area need".  

People in the real estate industry getting together online -  socializing, networking, helping each other out, and making deals!!!!!

You have to market the property on social media sites and direct booking helps.
