Once you know the costs of renovations you'll save money and a headache in the end.

I realize I am a little late to contribute, but we renovated 2 bathrooms in Nashville in an extremely short window (1 week) and can't say enough about the contractors we used. 

You should be able to do a massive renovation in just a few weeks if you have a good crew.I do agree with not risking bad reviews by listing on the big sites too soon.

Plans are to immediately sell after completion of construction and potential use revenue to start an even larger project. 

We have a few larger appliance vendors but they are expensive for minor appliance issues like seals, handles, and timers. 

Take my advice with a grain of salt because I myself am a novice, but I will say you may be doing a bit too much for your first renovation!

We offered $20k with my estimate of $50k in renovations, which for this one I will do myself (with some help from friends and family).

I specialize working with buyers nationally for larger multifamily and also retail commercial properties.Some are serial lookers afraid to buy the property when you do find the deal for them.Be blunt with a broker.

The owner was good enough to advance money and allow us to renovate the house to move-in ready condition. 

Who cares if you are “underwater” if the asset is making you cash flow...just don’t sell and you won’t have a problem.Also, the rich might still sell, they just might sell and re-leverage into a larger property.
