Essentially, one of us has the seed money the other has all the tools and contacts to rehab, repair, etc.

However, I have been using the BP BRRRR calculator tool for some offers I have made, and my question for the experienced BRRRR investors is this:If you rehab the property to the point where almost everything is new (roof, kitchen, baths, HVAC, electric, etc), why do you still need to factor in 50% of the rent as going towards expenses if you don't expect any?

I am ready to finalize this offer and would like to connect with anyone with  experience  in value add deals and financing.

I'd recommend using the networking tools here on BiggerPockets! 

What's a good way to test the accuracy of tools like the BP rent estimator and others?

Make sure you check out all that this site has to offer.The site has quite a few tools that can be helpful for new members.

@Elijah Crew, leverage is a powerful tool.  

@Deepak AroraIn California, given today’s market conditions, the difference in value seems to be negligible.

There are some great study tools that can help you retain the material, but you do need to make a commitment and put in the effort to prepare.

I focus on low-moderate income residential and have seen a huge increase in value across our holdings over the past 3-5 years, so we wrestle with selling all the time.
