You point to contractors suggesting specific mortar materials being used but can you identify in the building code a requirement that these recommended mortar materials are utilized?

Remember your costs will be more for an STR, you'll be paying for a lot of things you wouldn't with an LTR - higher STR insurance, all utilities including internet, supplies like toilet paper, paper towels, dishwasher detergent etc, upkeep on furniture and linens if damaged, yard maintenance and grass cutting/snow removal, trash removal, etc.  

Me, my partner, and our CTO are building a platform that utilizes AI for all people to sell and buy homes.

Utilizing bonus depreciation and cost segregation can be a great tax savings strategy. 

First step is to check with the city or county to find out what the zoning is and the allowable uses are and what is required for development in terms of lot coverage, setbacks, height restrictions, utilities, access easement, parking,  etc.

List all your known expenses (taxes, insurance, utilities, etc.)3.

I called my local Probate Court and the Court Clerk but they had no idea what I was talking about or where and why this information would be public and referred me to contact each individual estate.Has anyone utillized a Lead source online for probates that is reliable?

If there are hiccups along the way, such as a long vacancy, my staff is trained to call or email the landlord with updates (weekly is the default, but some landlords don't want that).A five-month vacancy cost you $7,000 in lost income, plus utilities, landscaping, and other expenses.

Look at everything, from utilities, to landscaping, to property taxes etc to see where you can save.

Similarly, if vacant, inspect the property to ensure utilities are off and the doors are locked.
