I would expect that these explanations can vary pretty significantly when described by someone who is just starting out vs. someone who has a few notes under their belt, to someone who has scaled their business; the more responses the better!

If you sell and buy a new place, u'll lose money on closing cost, realtor fees, vacancy during buying/selling etc.i would only sell if you want to move to a different state where cash flow /appreciate is better, or if you want to avoid a potential scenario you see coming that's bad (i.e. housing crash that would hurt a lot in your state) or if you have so much equity in it you think you can scale up, ie. buy several SFH with it and still get +ve cashflow, or buy a quadplex with it.i did a similar analysis earlier on a property i purchased in 2015 for $200k, it's now worth $280k, and i did nothing to it.

That's how I got started and scaled my portfolio exponentially one year later.

Scaling a business quickly requires taking on enormous risk.

I also want to be able to put my hands on the first one and manage it so that I can better scale the business for the future.I wanted to see if you guys would be willing to take a quick look at the deal that is going to allow me to quit my day job, and pursue my dreams.

If you want to scale the business to support your family then the number one thing you have to worry about is leadgen, and so that might be the first place that you look to invest that money, whether it's direct mail to pre-foreclosures or online ads.Leadgen for wholesaling is more difficult than for retail sales so you could use your license and focus on on-market sales in the immediate future, while figuring out the off market strategy.

In the end, I helped the two partners create systems in their business that allowed them to scale fast and triple the number of houses in our portfolio.

Now if you were going to pay it off in 5 years go with the low rate.I agree, but I am looking at a large scale.
