@Kris MayorIt is possible to get owner financing and there are web sites where the owners list properties directly BUT with rates so low and it being a seller's market in your area, it will be tough to come by.

I found that US Bank offers personal lines of credit for $5k-$20k at 10% interest with no annual fee.I figured it wouldn't be a bad idea to have access to this for a rehab overage, black swan event, etc.Does anyone know how simply having access to this, but not actively using it, will affect my personal credit?

I should have waited and had more cash of hand before i made the investment, they are boarder line in the black.

It will tell you how to break it down.Go multiple houses determine what needs to be done in the house, what need to be updated etc...Make a list.Then use calculators like home depot ones and spend some time in hode depot web site to decide material cost.After that you need to determine your scope and talk to plumbers, electricians etc.Have some kinda a scope and details list for them.You should be good to go.You need to spend some time, nobody can tell you exactly what it is.

Taxes can be obtained from the county appraisal web site.

Is the tenant responsible for re-caulking the areas in the caulking in the bathroom that have turned black due to time and regular use?

Ive seen web advertising for this before, ive never applied but Id like someone who has gotten it approved to chine in.

Are the walls currently black or maroon and need a few coats of primer then your wall color? 

You need to readjust before you get yourself caught in someone's web selling you a course or mentorship.

Otherwise, you can just insulate them with the black insulation foam.
