Permitting upgrades was interesting, because of their size, there are multiple code violations that were "excused" since they are grandfathered and the inspector could not recommend a solution. 

Obviously it would be in the Buyers best interest to have all disclosures and previous reports on hand before the Buyer pays to have multiple inspectors look at the home.

Have multiple "outs" should the market change mid-flip. 

Seems unlogical to take a property that I paid for at the bottom of the market and then take the equity and buy at the top of the market, but if I can own multiple properties or do something else with it then maybe the higher debt amount doesn't matter? 

We made an offer on another home yesterday and it went into a multiple offer situation. 

Putting an offer in on a property that may be getting multiple offers.

The answer is going to be doing the legwork to talk to multiple lenders.

My sister wants to get involved and will be helping by assisting me in whatever reno projects we can do ourselves (probably just painting, tiling, flooring, and basic stuff to save on labor) and by letting me use her good credit for finance options.

I self-manage these properties, doing reno work myself and liked how little I need to get involved.
