24 YO going into second deal(LTR,MTR,duplex,4plex?)

[Ira Frank jr]

Hey everyone, My wife and I are 24 years old and we are trying to make a smart move into our next real estate deal-but we feel stuck between a few different directions and would really value some insight.

-no consumer debt

-currently have one cash flowing LTR in WI

-goal is to scale 20-30k/month cash flow long term

what we are debating:

Another LTR(single family)

STR purchase

MTR

Duplex/Triplex

Value-add/fix and rent 

what were struggling with:
with interest rates where they are, were unsure if we should prioritize cash flow vs appreciation vs scalability

We don't want to complicate things early but also don't want to play too small

My main question: if you were 24 again with capital and one rental already-what would you do next and why?

I would appreciate any advice, especially from those who have tried many strategies and can speak on what actually scales and what just looks good online.

Thanks in advance
