Has anyone had success in buying down rates on single family with commercial loan?

I am looking to learn about note investing and also looking to buy 1st position performing notes. 

Add into the equation the cost of materials and it makes sense that builders are finding ways to cut overall build costs and one of those ways is to buy land cheaper. 

@Andrea Evans I think:Worst Part - Lots of pitfalls you can fall into if you do not know what to look for like buying and property taxes double, suburb rental license, buying a property with violations, not understanding the importance of lease documents, etc...Best Part - There is so many opportunistic corners or niches in the city and suburbs that most out of state people do not know about and out of state investors never get to cause they get caught looking at cap rates on the south side and in south burbs. 

Investment Info:Other buy & hold investment.

Hi everyone, Just joined today, and I'm from south africa Cape Town to be exact i think I might be one of the only ones on here.Just starting out and looking to buy my first property soon...

I'm not sure if I should buy another home or I should add the 40k to the duplex down payment. 

Have you communicated your buy box clearly and the areas you would like to invest? 

We have favorite title & escrow companies in each of the communities we buy in.

Don't believe me, go buy one and see how it goes.
