My wife and I are both teachers and I also coach three sports to help make more money. 

Thanks.Why are so many wasting their money on courses.

They have worked for money and appreciate it. 

Up to this point I haven't shared with the homeowner the exact amount of money I stand to make on it -- only that I have options to profit off the sale.

That's if we're thinking strictly Houston, but for such a budget I'd put that money in a diff city or diff investment vehicle.

@Trevor MorrisIf you are looking to do value add renovation for your next investment, a HELOC seems like a great move. so long as the other investor is okay with loaning out the HELCO money as well. 

Is there anyway to get rent money same day?

The main strategy I am studying is the BRRRR and how we can apply it to the spanish market and laws so the investments can be replicable again and again without leaving big sums of money in the deals.Nice to meet you and hope we can help out each other and other Spanish members.Barry 

You certainly 'can' work directly with the builder, but you will NOT save any money by doing so.

SAVE SOME MONEY.
