I can imagine it may be quicker/easier to sell but cannot see it actually impacting the value of the house as it is still residential and not a commercial asset.Thank you!

This allows scaling much quicker than cash flow.The appreciation in San Diego RE has historically far outpaced the great cash flow markets return from cash flow. 

Rather than refinancing, there are advantages to a HELOC (low closing costs, quicker underwriting, and I only pay interest on the funds I use).

We could've been done much quicker if I was little more hands on, and it could have afforded us to sell a few months earlier when the market was a bit stronger.

Hard money will be easier/quicker and non-qm will have slightly better terms but much longer process. 

Deals also close quicker, and the seller walks away with either the same amount or a little less money than if he sold it the traditional way, only they received their money in 2 -3 weeks and don't have to wait months at a time.

Escrow Officer or Title Rep - having a good one on the team helps to close deals that much quicker.

There are plenty of people in this business that will take a deal quicker than they will find a deal!

I personally prefer the inhouse loans to the secondary loans just because my banker is so much more flexible and I can act much quicker on a purchase.

This will be a tough market to negotiate with but you'll likely have quick decisions, quicker sales and best of all, repeat customers that will keep you out of trouble!
