Instead, you have to sort through every item and decide whether it's household in nature (cleaners, clothes, etc.) or of "family importance" such as photos, certificates, etc.

Occupancy in single-family residences where the owner(s) are natural persons or their estates, who own in their own name, no more than ten single-family residences subject to a rental agreement; or in the case of condominium units or single-family residences located in any city or in any county having either the urban county executive form or county manager plan of government, no more than four.'

(In other words it’s my job to make sure everyone gets in and out of the deal with money in their pockets and not in “unexpected mishaps.” cause if ya get the #s right in the first place there shouldn’t be any reason for something to take ya off track) Although you mention having experience is a leg up, but as a man who works as a welder fabricator/ plumber I obviously have none other than the research I’ve been doing independently for the last 6 months.

I'm not saying you can't find something in the 3s or 4s - always good to shop around, but the nature of lending is based on statistical rate of default, and owner occupied properties are statistically less likely to default than non-owner occupied. 

I have several investment properties and have a weird one here.My tenant, who the lease is with, passed away from natural causes in the summer.

Account ClosedThe best write-offs are payments that you would have to pay regardless if you were in the rental business or not.This is allowing you to shift payments that were generally personal in nature but because it was also required in the business is now an eligible business deduction.

Unfortunately I'm not too sure how it would work in a different country due to the difference in contracts and things of that nature.

This leads me down a rabbit hole:This is likely a very old house.It likely has some deflection in the floors (so you are never going to fill gaps and have the filler stay)Wood joints aren't true any longer due to shrinking of a 100+ year old materialYou have a number of different patches if looking across all of the pictuers.So, the last thing I would do is refinish this floor with a natural/stain finish.If it was a section 8 grade rental or similar, I would do a sand, vacuum, and paint with a flooring paint a brown.

You will need to develop that look if to doesn't come naturally. 

@Luke H.There have been multiple well thought out responses albeit of a vague and generalized nature based on the limited initial information provided.
