I also haven’t had to deal with the court system but when dealing with the City of Stockton for permits, they’ve been great and fast compared to some surrounding cities!

Here's a list of stuff that went wrong because lack of experience costs time/money when you do a DIY project:Car broke down because I used it as a truckHad to get a GC registration with the state of Rhode Island or face violations from the building inspector (5 hour course, pay for insurance, and taxes, around $2000) because here you can't pull permits yourself for anything and you need permits for everything other than painting or putting up shelves. 

I did all of the work myself, fully legal and permitted. 

The permit and environmental process can potentially be a nightmare. 

A STR that is in a good and allowed area can make 3 or 4 times what a LTR makes in a month.A calculator can't tell you about an area, amenities or local attractions.It also can't tell you if it is legally permitted to be a STR.

Owner financing was also the better route for both parties as a result of dealing with the state in transferring permits and operating rights on the water well and sewer system, which is a slow and arduous process.

@Mallikarjun Reddy Pateel  I would also ask for city permits signed off by every department (HVAC, electric, plumbing etc). 

Asheville has a near-ban on all Short Term Rentals, so don't even look in the city limits because it's almost impossible to get a permit.

I am leaning towards the idea of STR but from what I am understanding there is a permit process for unoccupied vs. occupied.

Have you had any issue with the city of Newark’s requirement of having a permit for 3 or more non related tenants?
