That's why appraisers do the comparative approach and then secondarily the cost approach.So far, 100% of the time you don't get dollar for dollar back from what I've seen.

I am not familiar with any HML on a fix and flip that would not want an appraisal as well as an estimate of costs.

Property taxes and insurance costs are best obtained through local county websites or reaching out to insurers directly for quotes specific to the area.Tools like BP Pro and Reventure can be helpful for an overview, but it’s a good idea to validate their data against primary sources to ensure accuracy.

I want to know is it more cost effective or easier to purchase the property alone and put it in a mortgage in our name or purchase the LLC from him that holds the property within it.

I have "XXXX" of debts every month, and make "XXXX" every two weeks.That will find the cost of duplex you need, though you may need to verify it is using current FHA guidelines as they have changed recently, so make sure you use that. 

They’re upfront about timelines, costs, and any hiccups that might pop up.

@Shayan SameerThe non-paying tenant could impact your short-term cash flow, so consider the potential costs and timeline of eviction in your state.

Next up is a huge financial hit: closing costs.

Seems like it's in a lower end area so if it is filled you will have tenant issues and turnover cost.

It's a good practice to overestimate costs and underestimate after-repair values (ARV) to keep your expectations realistic.
