The nicer the place looks, the more likely it will attract quality renters willing to pay market rate.

You only have to pull in a few people to make piles of cash without producing any results . . . it is easy to blame the person that paid for the service for not spending enough or working hard enough.

Demand for housing in Bali exceeds availability, and favorable construction costs, salaries, regulations, and taxes make Bali an attractive destination for real estate investors.As @Benjamin Werner mentioned owning property in Bali works a bit differently than you probably would expect.

if you do a search on the recent forum posts you will find Ohio mentioned a lot as attractive places to invest, make sure you do due diligence and also have boots on the ground and connect with realtors and investors in that area.Hope this helps and I wish you the best!!
