I want to ensure that I follow any sort of regulations and safety standards but I don't know where to even start or know how to estimate rough costs.

A buyers agent, even if compensated by Broker for Seller, will represent the interests of the buyer.Under : "Sellers Estimated Costs" she's got me paying $1,925 in fees. ($675 preparation of deed) ($650 transfer tax) ($300 settlement fee) ($300 notary fee)Also in "Sellers Estimated Costs"  "brokers fee" is listed as "$4,000"   rather than 6% or $4,000 as if the 4k is just a flat rate.I feel this gives her no incentive to sell my property at the highest bidder.

Does Anyone have any recommendations (and/or referral for an estimate)  on a rehab needed for a 5 BR brick townhouse that needs a bit of everything for a flip. 

I do not have much knowledge on real estate but I am the hitting  books: BRRRR by David Greene, Estimating Rehab cost by J.Scott, Investing real estate with no/low money down by Brandon Turner and finally, Rental property investing by Brandon Turner.Outside of real estate, I enjoy swimming, bike riding, watching anime, playing video games and interests in the stock/house market.Excited to learn and connect with you all!

Cosmetic renovations are easier to estimate rehab cost and are still considered "turn-key" to sellers.Happy to connect about any renovation or construction needs.

What was missing was a estimate for what he recommended. 

Can anyone give me a estimate of how well mediums do on average? 

Sometimes fixers need more work than you estimate.

You can't go off of the cost estimate on permits and even beyond that, design, site work and a number of other factors will play a significant role in costs.

As noted in the prior post, not really much you can do about going after an appraisal as its an estimated value at that point in time.
