With this strategy, the house layout is very important.

Don, I agree with your list being dangerous, but none of the top five are what I would call mainstream strategies.

I work mostly with investors doing just what you are seeking, the BRRRR strategy.

Here are a few high level thoughts for you as a beginner:-Don't lend in second position-Don't do deals with new investors-Don't experiment with new strategies, even with experiences investors- ie, don't jump in to a first development project with someone just because they've flipped 20 houses. 

If you want to chat about best strategies to get that 2nd and 3rd property let me know!

I'm finishing renovations on a studio apartment (under another unit in a multi-family) in the next few days and am trying to decide on what strategy to use to rent it.

Also, banks typically use a valuation process that does not favor the BRRRR strategy. 

I really want to do an apartment building but i want to build a track record first of smaller deals and just looking for a strategy to get into deals similar to a subto or wrap.whats an agency loan?

I only know my market, however I am certain marketing and pricing strategies will be key to filling those units up as quickly as possible.  

Are you looking into certain investment strategies to begin or certain markets?
