The floors were extremely unleveled and the new flooring was already coming apart, in one unit a previous landlord spray textured over every surface of the property including the thermostat/door knobs/trim, in both units the kitchen and bathrooms were falling apart and barely above usable condition, the staircase in one unit was obviously illegal it was so steep, and the walls/ceilings in both units were a mixture of poorly cobbled together panels, cracked lathe & plaster, suspended ceilings that should have been replaced a decade ago, and entire surfaces made from something I couldn't determine.  

. (;-) are you sure you are not missing a Zero on the Purchase price - $145,000)$30k for cosmetic renovation on 8 units sounds low. i just did basic to reasonable standard (check my BP blog) and it costs 5k per door. no new kitchen or bathes but re surfacing and granite tops., Viynal planks hardwheres thorough, signage and light fittings, fencing etc.

@William Webb Many of my lessons learned have to do with tenants and I'm quite sure I've just scratched the surface with this.

Although the numbers look better on the surface for these low cost homes, you end up with much higher expenses and more tenant problems.

When you dig down, don't forget that plumbing drainage has to be addressed.

The surface beneath the current floors is a concrete slab that looks like used glue to hold the parquet tiles down.

Every surface had to be touched.

Should be cheap, quick,and keeps good drainage away from your foundation.

(I recently had a buyer back out because they found out that sheds were not allowed per HOA CCR's)If you reserved the right to have a survey conducted, you may be able to terminate the contract if something shows up on the survey that is not acceptable to the buyer (a drainage or utility easement that was unknown, a fence that is over the property line, etc.)Deals can fall apart over financing, as well.

On the surface I would walk from this deal.
