Now, I am working in the sales department and learning loads of information every day.Look into the property management companies in your area!

In case anyone wasn't aware, Providence's new regulations on AirBnB and other short-term rentals will go into effect November 30th, 2019.See the short-term rentals page in the City's Planning department website for a human-readable explanation of the changes (complete with flow chart), or the actual ordinances here (defined on pg 20 as "The occupancy or use, for a fee, of all or portions of a dwelling unit by anyone other than the owner for a period of fewer than 28 consecutive calendar days", but the regulations are on pgs 102-103).

Start with the potential gross income and work backwards from there.Check with the city or county planning and zoning department to get an idea of what you can build and what is required for all approvals including site plan and building permits, proffers, water/sewer tap fees, bonding requirements, inspections and CO process and time frame for all approvals.You also need to check with the utility companies and get an idea of availability and cost estimates from them for water, sewer, power, gas, cable, installation and connection requirements, tap fees, hookup charges, transformer location and relocation, power line and power pole relocation issues.

Now that you're in the "has done an IRRRL" databases, all these random cold calls you will get making mention of them being from the "special veterans benefit department" (I get the same calls) are actually just VA IRRRL churners, and when I say "you're wasting your time, I'm a mortgage broker," they just keep reading their script.

  -  Homelessness...I will just quote this part as I can't do it justice   "My Department of Justice will not fund efforts to criminalize homelessness and will deny grant money to police departments who are arresting residents for living outside." 

The seller is The Secretary of Agriculture for my state, which I thought was a bit peculiar.The property you are looking at was funded by a loan from likely rural development, which would be under Department of Agriculture.
