For being your first deal, renovating 4 units in 4 1/2 months is extremely quick, so you should be happy with that success.  

I have purchased several deals where the house was just a shell and had to rehab everything from plumbing to electrical to roof , etc. it's a massive headache and extremely time consuming.

Thanks to this wonderful community and all you wonderful people over the past few months my wife and I have gained the confidence to pull the trigger on this exciting adventure.  

He's extremely professional!

@Dan LieffortUpgrading to an HVAC/ Central Air isn't a necessity, but renters want them.Window units are extremely inefficient and cost a ton to run the majority of the time.In my multis I get more money per unit 100% of the time.As far as cost goes I would just get a couple of GC's/ AC guys and go with who you trust to do the work, has competitive pricing, etc. and keep your tenets happy.I can refer you to people if you need.

Chances are a dog will do more damage than the deposit will cover as most renters are extremely irresponsible.

If you have personal experience with the PM, that'd be extremely helpful.

Thank you, that was an extremely helpful response!

Now mortgage debt owed by U.S. households is about $8.4 Billion.I do agree with you that there are a lot of extremely reckless "investors" out there.

@Christopher BrainardI extremely appreciate the solid advice.
