She was overwhelmed and needed help, so we stepped in to take care of everything for her.What made this deal different was the level of support we provided.

Your new build may be in good condition, but a lot of tax sale properties are not in the best condition (people who can't/don't pay their taxes also often can't/don't take care of the property).

And I noticed that many of the unfurnished units were offered with a month to month lease... the kids would get cheap furniture that they didn't care about tearing up and giving away when they were done.

Otherwise, just say 2050 to be safe, but realistically, no one is going to care/notice and if they did, you have paperwork to back up your number.

One of the side benefits is that the tenants now have skin in the game so to speak, and my gas bills have gone down a bit.What kind of heating system do you have in your property?

You can edit it, but be careful to not get too cute, the quality of your contract is the quality of your deal.2.

Tenants and investors in general don’t care for their buildings as much/well as residential owners  (who fights reserve increases and special assessments the hardest - investors).

but it sounds like your mind is made up on this mentor.. flipping right now is a pretty tough gig for a beginner depending on market. very low inventory then sky high rates for your buyers. so use caution be careful also make sure you have a GREAT RE Broker who knows the values and what you should and shouldn't do in the rehab to maximize your returns. these things are very market specific U simply need to make sure your matching what is expected in the market you choose.. 

Who cares?

Just be aware and be careful.
