Most people cannot handle that kind of a grind and it can also be expensive. 

I also liked Retie Early by @Chad Carson not only was he a stud linebacker he knows his crap.While the millionaire real estate investor breaks down the grind of real estate investing Mr Carson helps you come up with a plan to become financially free. 

For what it's worth, I think it is not right to try to hang on to the prospective tenant unless you are up front with them and let them know the current tenant hasn't left and is making noise about not leaving.

Making the right hire for your business is important if you want to get out of the “day-to-day grind” of your real estate investing business so you can SCALE and DO MORE DEALS.If you are starting to do deals regularly and you have been down in the trenches alone doing everything, you may be realizing it is NOT the best use of your time to wear all the hats.

My tenant complain about every little things from noise I have given notice in advance 1, How do I approach to their complains 2, What is the appropriate time to start the builder to start working in morning 3, I put HVAC on garden unit and 1st unit so radiators were removed. 1st unit tenant wants their floor fix on radiator site ASAP.

It is this time around there is some noise. 

In my limited experience I would say that if you go virtual in a different market (say a smaller city with lower priced homes) you'll generate more leads, but you may struggle with disposition as there is less Investor activity from your potential end buyers (Small,Med, and Large Flippers, Institutional/Hedge Fund Buyers, Turnkey Operators..etc) On the flip side if you stay in the more competitive market it will be a grind to get those first few leads and to secure a contract but your odds of not being able to dispo it should drastically decrease (Assuming you have a discounted deal in the right area) and that check should be NICE. 

I think if you grind it out and find the deal and it is a good deal you will find the money.

Ideally, you want to find out about changes that could affect your view or noise tolerance.Neighborhood designations.

If the previous tenant didn't complain about the noise, the new tenant may be more sensitive to noise.
