Think about using a partner on the first couple of deals to build up your bank roll.

Germantown is a little faster than the village.

My network and experience working with international clients allows me to market your home to not only local buyers, but also cater the marketing towards international buyers that generally work with all cash, enabling a faster close.I'd be happy to help put together some comps for your sister's home.  

We knew the faster the foundation was built well, the more we could utilize exponential growth.

The properties that have a short DOM this way, set your sale price based on those properties, and you'll sell much faster. 

You can always pay more into the principle to pay off the loan faster (assuming you do not have pre-payment penalty).

The biggest one was that houses appreciate faster when a Starbucks opens up nearby.

However, i gave this guy about 8 chances, and this isn't a wholesale deal - its a me deal, and when I'm bankrolling something, I want results.  

All in all, a faster, cheaper way to close and if I am able to refinance then the line of credit is ready for the next purchase. 

Those are the ones that will help you get a better start, help you create a road map to go by, and can push you toward where you want to go faster.
