We don't feel comfortable about houseflipping because we have never done it and rather have a safer option.

Just look for a shop that will teach you the basics of real estate contracts, offers, MLS navigation, and disclosures. 

If the price to replace is within budget I'd do it because you're putting out a newer/safer/more reliable product.2) Cost to replace the entire systems is tough to gauge without knowing the building size and style...

And you'll have the ability to shop around with money partners especially once you have a few homes to show that you've built.

I’ve shopped around with a bunch of different skip tracers and what I’ve landed on for residential is using MLS data (Realist or Remine) or local County data to pull the lists.

As far as the lender goes, if I'm buying properties that qualify for conventional loans does it really make a difference if I build up a relationship with a specific bank vs just shopping around each time I buy a new property?

I'm deciding if I should shop around or does this seem pretty inline with other companies?

you can do it for less. 10k max. there are volume syndication shops you can use. 20k is high for a simple structure. depends on the structure. 

If you have time, go visit some of the homes and secret-shop them to see how they compare to yours.I recommend looking at the market at least once a month for the rest of your life to keep an eye on things.
