@Harvey CardwellLets lay out the options:1. 

I have attempted tile jobs in bathroom renovations, kitchen walls, and entryways, and have attempted carpeting areas, and painting jobs, among other finishing touches, and in almost all cases, the slightest imperfections are easily seen and have defeated the purpose of trying to save money by doing the work myself

I recently did a tile job, changed the scope of work and needed more tile for the backsplash, went to the store and they were sold out, I lost a few days just like that.Forrest Faulconer

I have one successful flip under my belt and 11 rental units that are profiting well.I am looking for advice as to how to structure this or lay this out?

I can't put a new tile floor on top of a rotten subfloor.

It currently has carpet everywhere with the exception of the bathrooms and kitchen (tile).

Within two weeks, the tiles began coming up.

Don't gut and re-tile and spend thousands. 2) If a roof or hvac is not at useful life (even 13 years old like our last house).

As such I'm somewhat handy, but also know where my limitations are (for example, I'm not a tile expert) I'm also very clear on the fact that I'm not licensed as an electrician or plumber. 

Laying out your goals is also essential, because sometimes that can help the loan officer determine what the best rate to give you.
