This is my first investment property and I plan to BRRRR it and convert the garage into an ADU / jr, ADU.

I do think that mid to large size B and C class office will struggle as we start to see office users move to shopping centers (Amazon is converting a former Sears at a mall here in my market) The C Users move to B and B to A and A to new build or shopping center conversions.

If thats not an option, maybe focus on properties where you can add some value (i.e. convert a 2 bed into a 3 bed house which could increase how much you can rent it for), find a good wholesaler who finds off-market deals, or look elsewhere.

Its already been converted to gas He Can get at least 1500 per unit.

The value is converting the current tenants who are all on a month-to-month lease into annual leases and filling current vacancies.

Torey-The easiest way to convert is through Adobe PDF software. 

These sorts of additions can sometimes be converted into separate units (either full DUs, ADUs, or JADUs) without incurring the full cost of construction. 

Especially the side by side ones that were actually built as a duplex and not converted SFHs.  

I had my first vacancy in December and used that time to renovate the property by replacing all the flooring, converting the den to a 3rd bedroom, and some other cosmetic and minor structural repairs.

This double structure with master lease is important to convert the str income to passive income.
