I wanted to share the numbers and want to make sense if it's a good deal for us according to what we are looking for.Price: $450k (agent said that we can get it down to $420k)2 Units (1 bedroom in each unit)Mortgage with 3 year fixed comes up to around $2.3kInsurance and tax is roughly $400Rent per unit is $1.4k so if we move out then total rent comes up to $2.8kThere's a detached ADU (garage) that can give us another $100-$150 if we rent it for storage and there's a scope of converting it into another unit later on.So currently rough calculation says that it can cashflow up to $300 per month.

I have been thinking small office or retail (which I have experience in); larger multi family (10-20 unit), RV Storage, and have even thought about beach front hotel, or at least ocean view hotel.

Given they are going to damage the walls while moving anyway it eliminates their need to touch up the halls and I can usually schedule to have one painter knock out multiple units in a day but even if its a one off sale, it comes across as good service for a small amount of money.In a storage area within the house or garage I will leave an unopened box of each tile, and flooring used in the house along with unopened 1 gallon buckets of the wall and semi gloss paints and one of each door hardware (kitchen and interior doorway.

It might seem like a kindness to provide a printer to a traveling professional, but until they invent one that works on every device, every time; that doesn't need paper at two in the morning; and has cheap toner that refills itself, we will pass on that amenity.I am sure there are other examples for all 4 quadrants, but like @Allen Duan wrote the important thing is to look at amentities through the lens of the end user (with an eye towards the "competition").

Although we could continue to add to our Self Storage investments in the US.  

Can I charge them fees & rent for storage of their crap? 

Seller used one of the units for storage.

I’ve focused mainly on Florida but have also looked at options in Sacramento and other slightly more remote locations in CA.While I’m familiar with value-add strategies (ADUs, renovations or storage rentals), these seem like heavy lifts for modest gains.

This is 5 mobile homes and one building being remodeled as a storage unit. 4 park owned homes and 1 tenant owned home.

If we do a Self Storage development we expect a 400% COC return.
