These units need some paint, some carpet cleaning, and the top boards of their decks replaced.  

Reserve cabinet in kitchen for each room and set a schedule for clean up.. rotate chore chart, like week 1 ,,room one does bathrooms, room 2 does all vacuuming, room 3 all trash out to curb, room 4 mowing and rotate.. 

All,I have a rat problem that has been in one of my houses for awhile, unknown to me and I have to get it cleaned up.One company I'm working with says I need to remove all the insulation, droppings, clean and treat and reinstall new insulation.

Many times things like faucet sets and even door hinges will not clean well, they can become pitted from corrosion.  

Give them a good clean home at a fair price and make sure you don't overpay for whatever you buy and you will succeed.  

We also can't prep our side for her properly until our stuff is out (cleaning, paint touch ups etc.)  

@Asim Alam higher average rents (could be easily 2x-4x more depending on property and location based on some properties I've analyzed with an AirBnB in mind), but also higher vacancy and turnover costs (although some turnover costs are mitigated by an added on cleaning fee).

Clean up exterior, freshin up exterior paint, put ownings on, do easy maintenance landscaping, add a coin operated laundry for additional $100 per month at $1.50 for washer and dryer each, increase rents in between tenants or at anniversary dates. 

@Lou Ruggieri,alternative thinking:-clean basement floor to perfection-waterproof membrane/ couple layers of exterior grade paint (encapsulate any asbestos dust)-exterior grade carpet : because you are up north/cold floors; if flooded, can be taken out, disinfected and hosed out, dried out, replace backalternative thinkhing2:-clean basement floor to perfection-waterproof membrane/ couple layers of exterior grade paint (encapsulate any asbestos dust)-treated 1x1 (as "ribs"/"joists")-lay exterior grade plywood/ost on top of it-floating floor on top of that: preferred here is Allure LVP from home depot, but many available from reputable manufacturers; probably floor needs to be rated for under grade/basementsortile everything and provide rugs + non-slip underpads

Hi everyone I am a new investor but I am also in the process of setting up a residential cleaning business.
