I'm reaching out to see what people's thoughts are on how they might tackle our situation. 

Instead, I’d like to enlarge the existing unit and add a second unit, and keep the units as a rental over the long run.Which would be the best professional to tackle this layout?

@Jesus Hernandez You have some great advice to tackle the Buy and Rehab phase of the BRRRR, but what will it rent for once you have completed it? 

I did not renew the lease and rehabbed the apt when they left.well the cat piss went into the hardwood floors and made an expensive rehab more expensive to tackle the floors. 

It's not a calendar app, but fits a huge part of what I need as far as being able to brain dump tasks when I think of them, quickly, and no matter where I am, then keep organized with anything that needs tackled.

Or if you bring an experienced partner in to tackle a large deal it may be viable also.

@Dean Fiacco I'd suggest you tackle this issue from a Collective Lease approach. 

I would also recommend reading "Who, Not How" which focuses on leveraging others and re-shaping how you think about tackling problems.

:@Steven Wilson good to know...partnering with someone experienced is something I am very interested in Or you could tackle it with cash if you got it! 

Anyways, whats best way to tackle this issue.
