Hey guys I'm new to all of this, so bare with me.My family partnership (of which I am a 25% owner) owns a 7-unit apartment complex in Southern California free and clear.

My expense might be a little low, considering the condition and the complex is like 50 years old.

. :)For a start, there this is an old or perhaps a historic complex in Dammam, Saudi Arabia (Built as a shelter for Kuwaitis during Gulf war, so it is almost +20 years old) which now totally owned by individuals, yet remains partially managed by the government.For many reasons, I find it a fantastic place to start with (among others) my investing journey where I need to learn about rehabilitation in particular, however, whenever I get to inspect an apartment there, I am always faced with one resisting issue, bathroom ceiling.

Particularly if they're side-by-side, look the same, look to have been constructed at the same time by the same company, share amenities and parking lot and gas meter, and maybe if the seller has put contingencies in place stating they must all sell together.It is not uncommon for an "apartment complex" to be a series of buildings, sharing a parking lot, amenities, etc., even the electric bill sometimes, and nobody would ever dream of parceling it out and selling one building at a time to different buyers.

For an older condo resort complex, unit slept 6, gross STR income was increased after renovations to between 30-35K per year.

One part is rent control and for now that only applies to apartment complexes with more than six units. 

After updating it should rent out at $870 (mirrored unit as the other that is at $870).I've enjoyed bringing this complex back to life and have a couple other options to do the same to others but would need to dump this one in order to do so.  

That being said if you are hiring a designer it all depends on the project, budget and complexity of the designs and selections.

Because parters essentially have to be "beneficiaries" rather than partners which is complex.

If you aren't 100% comfortable with how it works, and you're in a tenant-friendly market (i.e. more complex procedures), then you should work with a housing attorney who knows the process.
