What were the biggest line items?

As a fellow West Aussie who's now living in the US, I can tell you this forum and most of the training/courses you'll see online regarding multifamily investment isn't relevant/applicable in Australia.

Bringing in a partner, second mortgages, line of credit are sources of additional funding to close. 

Never built in Houston before so take my feedback with a grain of salt but I'd put money on it being impossible to build a duplex from scratch for $125 a foot (including everything from drawings, engineering, permit fees, general conditions, labor, material, landscaping).Out here in AZ the builder cost is going to be $200 a foot at best, but add 20% on top of that for the client cost.

@Juliann Morala Yep, a buyers agent that works exclusively with investors will have all the info you need and lots of options on contractors, lenders, attorneys, inspectors, property managers.

Most 1099s are available online now, and if not, you can always scan them to an electronic format.

A few tips I’d recommend as you get started:Build a solid buyer’s list early on.

Lots of valuable insight on this thread already..Since you are an agent, you are in a good spot to source, close on, or sell potential BRRRR deals. 

Congrats on turning that boutique motel into a success!

Have these guys ever heard of Quicken or any of the online personal finance programs available to track spending?
