So they could give a better idea of costs for repairs as well as new furnishings etc. that may be required.

Also keep in mind, most houses these days are already priced well with the cost of repairs in place and trying to get anything or even writing an offer under asking price is pretty laughable today.

Put about $20,000 or less in repairs, then sell it on MLS for about $220,000. 

What most fail to do (which you haven't), is underwrite all the other expenses like property management, landscaping, repairs and maintenance, capital expenditures, etc.

Same for a collapsed sewer pipe - they won't pay for the repair to the pipe, but they do need to pay for the damages caused to access that pipe like removing flooring, drywall, concrete, etc.

Class A-D results shouldn't matter in the level of oversight of property (even before tenant placement) and quality of repair work.

What kind of loan should i go with assuming it needs repairs?

Minimal repairs and focused marketing ensured we didn't miss the opportunity to flip this property within a single day.

They have higher financing rates and costs since lenders consider the property's after-repair worth.

Got it.What we include in the process as well, is "how best to protect yourself from the "due on sale", what happens if the renter stops paying, what if the seller won't vacate, how to get a title report, why to not use a real estate agent, how does this affect my taxes, what makes for a good deal, what exit strategy to use, how do I hold title, what happens when the seller comes back later and demands to be taken off of the loan, how do I hold insurance, what happens when a roof or waterheater need to be repaired or replaced, and on and on.
