I think that as long as you research and implement proper systems, then dealing with the existent tenants in the units won't be too bad after an adjustment period and it will help you both in the long run; if they're running well he can buy more and pass them on to you and with proper systems in place, you can take on more with little to no extra load! 

My husband is an assistant coach for the kid soccer team and his work prevents him from attending every practice/game.

@Peter SlivkoffDepends on where you are buying in oregon.In portlamd city limits, for example, rent control prevents from raising 10% or more in a calendar year.Further, portland prevents no fault eviction.

A probably-OK way is to install a GFCI outlet as the first outlet on each 2-prong outlet circuit; it's not quite as good as having a real ground, but it helps prevent some possible failures.A 1970 house may not have been born with a dishwasher or Disposall.

Can only move forward from here.Moving forward action steps to help prevent this from happing again a few thoughts:Further condition:Current tenant(s) to sign lease with new property management company prior to closing.Tenants to be informed of property management change 7 days prior to closing.Closing contingent upon current tenants remaining with the property post closing.Would love to know what your reactions to and or response would be to this.

I do a lot of preventive maintenance right away to limit some of the surprises. 

@Michael SchmidtAs others have mentioned, the rules that affect retirement account investments will prevent you from investing your Solo 401k into your own syndication.

Fix that preventatively if possible, work on renting your property before the current tenant moves out. 

We've had calls from free legal aid and foreclosure prevention non profits who use the idea of the borrower filing BK as a threat to get us to give their client a loan mod.

For a property manager, they have more regulations that would prevent them from operating as a business without that business account.
