I have a few questions and I will definitely be seeking professional guidance as well, but wanted to throw this out in the forums.Background:  I have just opened a single member LLC. 

Guess what, people still prefer unattached single family homes on their own fenced lot.  

if ure 23 and single - house hack 100% get a multi unit live in one rent out the restcant afford multi - buy 1 SFH, multpile bedrooms - sleep in 1 rent out the rest of the rooms

By no means am I a local expert, but I think that the househacking is the best way to get started for almost everyone, especially a single person, or young couple. 

I primarily deal with single-family homes for investors looking to short-term or long-term rent, while my husband has a property flipping business.

I'm outgrowing my side and I want to buy a Single Family Home.Would I have to get a secondary home loan therefore having to put down 10-20%?

One thing to consider is the ongoing expenses is more than a single family home.  

We own a single family home in the last location.

Yes, a Single Family is qualified for a DSCR loan.

I don’t know about the Louisville market, but if you have to pay a bit more for the property than a traditional single family, it should be outweighed by the fact you will have a tenant paying hopefully well over half of the mortgage.
