Get Positive Cash Flow Every Month with One Time Investment

I and a relative of mine had bought a property and had decided to give it on rent and thus generate positive cash flow.
Places with very good tourist attraction are sure to fetch good amount as rent.  This had prompted us to buy a property in one such place where many tourists keep on visiting round the year or else like peaceful surroundings to live.
We were new to that place, but the support of a Vendor Finance had helped us to get a good property at a very good rate.  As it was just an investment, we decided to give it on rent and the Vendor Finance whom we had approached to buy the property also helped us to find the renters.  Apart from finding a renter, they also completed the whole documentation process in time and thereafter, we didn’t have to worry about the property or rent as they were very punctual.
What else did we want?  We already had a good property in hand and now, again with the help of Paul and Karen, we are generating positive cash flow every month without any fail.
