Always get monetary concessions... never rely upon a seller to do anything after closing, unless you want it done half-assed and on the cheap.

When the time comes to evict our first tenant, I will hire the best lawyer and let the expert take care of it.  

So that I find out doing my own calls to find out why the offers was denied even was just so close from asking price and Im willing to go with second offer, I found out that the place has reserve litigation issue and my agent who I rely on and keep emphasizing how we need to work smart dropped the ball again on me and didn't due enough diligence even he claims he knows how to do property searches etc etc which made me feel its an extra that he has, it was very sample to just ask the listing agent so not to waste my time neither his sending unnecessary contracts...

Not sure is seller will accept an offer with these contingencies as it will cost time on the market if the contingencies are exercised.  

Rinse and repeat a few times and you'll be set. 

Personally, I just communicate with my tenants that we keep the HVAC (in florida so rarely need the furnace) above 68 degrees at all times, and that it is best to keep the HVAC above 74 degrees during the hotter afternoons where the ambient temp is in the 90s.

As an agent, I always want my clients to know what their properties are worth because (of course) I want to sell the properties, but I also like people to know the best tax strategies. 9 times out of 10, you are better off holding the property for a while to get increased appreciation, cash flow, better debt, more cash flow, etc. 

Keep your time focused on what matters-- quality investments.

This was an old Portland style home so I used finishes that were reminiscent of that time What was the outcome?

Maybe they could help you out by being able to pay them over time.
