So my Dad lives in Indiana, where he and my step mom saved up their entire lives to build their dream home/bed in breakfast.

Walk across the street to Mean Mug for a quick coffee and breakfast.

It's not wrong but it's definitely not necessary or the best way.Go back and ask him how many checks he copied and then ask him how many times he needed to use one of those copies to save his bacon.

Renting out homes or single rooms – game day housing — is not permitted, unless the property owner remains on-site and operates as a registered bed and breakfast.Bed and breakfasts (Code of Ordinances 12.6.5.C.2) are permitted in residential zones, but only under these circumstances: It must be part of the owner’s permanent residence.It must maintain a residential appearance.It must be the permanent residence of the proprietor.No more than four unrelated people can stay there overnight.

As @Linda Weygant weighed out, a rental should not be subject to SE taxes unless it is short-term and substantial "hotel like" services are rendered -- e.g. daily maid services, continental breakfast, shuttles, laundry, etc.Your flips should be in a separate LLC. 

Is it worth it to offer a little breakfast? 

I spent a $100 this morning on one breakfast... hopefully that makes sense to you. 

The city already assured me they can work with me to make it commercial- bed and breakfast etc- Great potentials....

@Sean Wilt - I just had a little regurgitation and haven't even had my breakfast, thanks. 

These are just a few of the questions jumping around the grey matter every morning before being pelted in the eye with breakfast sausage released from the hand of the aforementioned toddler.
