If you are comparing the same exact interest rates then 20% will cost 1.625 -1.75 points more than a 25% down payment. 

We offered cash to be competitive with the offer, there were 35 offers in 5 days.

I have identified an ideal location, and the agent has informed me that the rent is $45 per square foot NNN, plus an additional $5 per square foot.Upon calculating the total annual cost, it appears that I would be responsible for over $80,000 per year.

And their investment at cost would be earning 17% + !

Our approach for implementation is to break all repairs into 4 categories by priority:1) Health & Safety - most important as could result in tenant lawsuit2) Property Preservation & Government Requirements - don't ignore a roof leak that costs hundreds to fix now, but will costs thousands in the future.

And of course a great BRRR lender who can fund on time every time. in my business I only work with experienced BRRR folks and as such I become a capital partner and allow them to scale with very minimum amount of capital and they dont make monthly payments. this is huge its the up front costs that usually hold folks back from scaling. so if they find someone like me then they can 10X what they are doing..

Costs the same to put on a new roof. 

Hi Ian,The best way to get this done is to refinance into a hard money rehab/construction loan.Not sure how much equity you have in the house but the ratio would be as following.75-80% * (Value of home+Cost of build/rehab) = Total Loan AmountWe would payoff the initial note (+ closing costs if loan amount exceeds construction budget & payoff), the rest would be in an escrow account for you to draw from as you complete your project.I would love to connect and discuss further on the details of this scenario!

Also, most of the stuff your list is low cost which is great, but once you start getting the deals and paying yourself back on the direct mail, double and triple those actions too (of course when you to a place financially that you can do that effectively).  

In addition I have yet to encounter a seller cost of value add being as high as my conservative cost Projection for the value add.
