If the unit is messy/dirty to the extend of being damaging or a health hazard, our lease also gives us the right to send-in a cleaning service at the tenants expense.Your biggest concern as a landlord will be vacancy - both physical and economic - as vacancy is foregone revenue.  

They want to lend money and get a good, safe return, they are way more interested in safety than making more than 15%. 

@Daria B.Livable condition includes things like the roof, plumbing, electrical, flooring, walls, ceiling, no peeling paint and cabinetry being in place and working order for someone to move in without a hazard etc.

However, if the roof is bare in spots, water damage shows, flooring is missing or is a hazard, etc. etc.,  then you're best off with private/hard money.

If the answer is no - for safety & security reasons, not just because you are too snooty - then maybe the property isn't for you (or at least wouldn't be for me).

Not saying they will lie to you, but everyone does their calculations slightly differently and may not be using the safety margins that you are comfortable with.

There's also companies that build "empty" towers and lease out tower space to a variety of other services (public safety, WISP, industry, etc.).

@Tou V.Be an investor and not a speculator-- for safety reasons.  

A stand and level may be rented and if your property is aslope, can are available in handy to stay lines of fencing level as you step down (or up) in several areas, safety glasses and smart work gloves.

Any health and safety issues?
