This is going to be an expensive improvement either way and I'm wondering what others may have done in the past who have done this.I've been advised that putting a grinder pump at each pad that connects to a central sewer line on the property that then connects the main line at the street is the best way to do this.

I think that as other competitors reopen their doors we will see terms improve (higher LTV for cash out, better rates, etc). 

Save up for repairs/mnx/vacancy/improvement ect?

Librarian for the city Applicant 2 has a 561 credit score but has obviously been improving as she has 100% on time payments, no evictions or judgments ect.. and can almost meet the 3x rent income on her own.  

My view (and i could be wrong) of it was to have the rehab done so it improves my future exit strategies. 

As for the second property you were spending money on making improvements during a time that it could have been redeemed and you would have had it taken away from you. 

I search for under managed properties so that with some refreshing, I can improve the rental income.

There's a controlled, pre-existing relationship (likely of a sexual character - but I don't know you and I'm not assuming) between the agent selling the property and the inspector who assesses its quality. 

Each with the same intention: improve the place and live for free.
