When I'm calculating repairs today I estimate what I think it should cost in 2019, then add 50% and hope I can find someone at that price. 

It is a straightforward flip that will take me approx. 3-4 weeks to complete and estimated profits are $30,000-$35,000.If I keep it as a BRRRR here are what the numbers look like:$145,0000 - Purchase Price + Closing Costs$30,000 - Improvements $1,500 - General holding costs (taxes/insurance/utilities)$2,900 - Loan on unsecured line of credit All in - $180,000Comps are around $225,000, which would put me right at $168,750 (75% LTV), this means I would leave around $12-$15,000 invested in the deal after the refinance went through. 

I know how to do comps, estimate rehab costs, and give the seller different ways I can buy their house depending on their situation whether its cash, options, lease options, subject to`s, seller financing etc.So, bottom line, if I can get sellers contacting me, I am very confident that, if their is ANY potential to do a deal I will find it, I just need to implement a system. 

These numbers are just estimates.

Here is what he sent me:Listed at 279k, units would rent for $725-750 each, taxes are $4,600/year, coin laundry income estimated at $1100/year.

Let's say, the property is priced up for 1,00,000 & there is an estimated repair cost of 20,000. which totals the money I have to spend to be 1,20,000. if the ARV is at 2,00,000.

If you don't have students, it's a good excuse for a quarterly inspection.Related to this, I estimated how long it would take to paint based on my previous experience painting and didn't factor in how much cleaning I'd have to do.

Either way show the inspection back to the seller with estimated dollar amounts for repairs and see if they're motivated enough to repair or adjust price accordingly. 

My house is currently, according to zillow estimated at 624000.

I am looking for a rough estimate for a 30,000 steel frame building 100x300 with 22' clear span.
