Also what are your goals, ie cashflow buildup, rolling equity into subsequent properties, etc?

If there is a fire or CO2 build up in one unit, toxic fumes will be transmitted to the other unit.

As a side note, I made most of the money to build up my rental house portfolio by flipping mobile homes in parks.

BRRRR is great because if you do it right you can just keep doing it and build up your portfolio.

Deals on good cash flowing multifamily are hard to come by and really depends what you are buying for (i.e. tax write offs, equity build up, cash flow, etc.)

Build up your credit.

Mostly DIY with specific trade professionals.My goal is to obtain cash flow to build up my portfolio and ultimately get time back from my W2 job.

Start slow and build up from there.  

I have ROTH IRA accounts that I could pull 10000k tax free from tomorrow if I chose to I have 30000K in savings roughly My current rentals together cash flow together gives me $1250/month ( this would take to long for me to build up more money in my opinion) I also have the ability to augment  my income at work through overtime I also have enough in retirement accounts to cover the 6 month PITI reserve requirements that lenders require for probably at least more 8 homes 

My ultimate goal is to build up a decent portfolio of SFHs.
