Determine the cost of construction (hiring a contractor in the GNO area is going to start around $165-175/sqft to build) and be sure to include all holding costs, as well as interest in the loan.

I studied RE development and investment for my MBA, I am the building inspector for the town where I live and I worked as a contractor before switching to only working on my own deals.

I've got a good amount of contractors I use for our long term buy & holds with heavy reno's up front. 

Quote from @Chris Kay: @Tim Ryan nope not a contractor so definitely need to find a good one.

Since you are new to the market, you can look at what the top rent pulls look like and cater accordingly on the design.You always want to build relationships with contractors, but that takes time and you always need a solid bench, just like in basketball because some days your starting plumber just doesn't show up and you need to bring in the backup.The rates are the rates and they aren't going way down soon so it's just part of a different metric to evaluate in your new market.Good luck!

please send me a case example I'd love to read. that's one appraisal. the knowledge I have as a licensed general contractor working with investors from 5 cities at a time all over the country buidling 3 different floorplans I would say trumps one ADU you read about online 

How do you know that a contractor is any good?

I’ve learned through experience that if a renovation will take several weeks or months to complete, it’s usually better to hire contractors.

Having a solid team around you like agent, lender, contractors etc.

Here is some key information:Property recently hit the market and has 2 cash offers alreadyThe seller provided a pre-inspection report, which I shared with 2 different lenders, both think it may fail conventional financing due to potential structural and electrical issues (realtor thinks it could pass conventional)Seller has 100% equity but is behind on other payments (not sure of the urgency money is needed)This is my first attempt at an “investment” property so I’m new to thisI see 3 optionsMove forward with an offer using conventional loan pre-qualification-Not as attractive of an offer to the seller-Possibility that appraiser calls out structural/electrical issues that need to be fixed before closing, effectively causing financing to fail- Best terms and fewest loan fees for meUse a rehab style loan such as ChoiceRenovation-Even less attractive than a conventional offer to seller, but less risk of failed financing if appraiser calls out issues-Slightly worse fees and interest rates compared to conventional-Lenders tell me possibly up to 60-90 days closing in some cases, with red-tape for contractor requirements and draw schedules (sounds like the most hoops to jump through during rehab)Use a hard money lender-Most attractive loan option I can give to seller so I can compete-Much higher fees and interest rate for me-need to refinance into a conventional at the end of rehab (not familiar with seasoning periods but I think this is a factor as well)Which option would you do?
