They may charge lower percentages, but make up for it in the fee, or charge higher percentages to include everything.

The mortgage payment on this house was roughly $1800/month so when we get tenants (or technically roommates while we're still living in the house) we figure we would have them split the rent evenly, or as a percentage of the house since someone could have the entire basement to themselves.

Move it to a new LLC to avoid old potential issues.You will both be members of the new LLC with percentage ownership.Have an attorney draw up the LLC Operating Agreement and be sure YOU understand it.

They charge a percentage of the winning bid or tax assessed value, whichever is higher.

All the ones I've called will get a percentage of what they collect and don't charge anything more.

If that is the role you are looking to file I'd think you would be paying between 5-10% of project cost.If you are actually looking for this PM to hire subs, write contracts, schedule, order materials...essentially acting as a GC....I would expect you to be paying between 15-25% of the project costs.I can't speak specifically to your market, but those are some ball park percentages based on my experience here in Chicago.

or as long as you have any percentage to be included for the "Funding Fee" to carry?

@Jamall Lynch I calculate a percentage of rent towards CapEx on all my properties including SFHs.

.: They can find a new partner that wants to put in $22,000 to fix the foundation and then collect a percentage of the equity later on. 

You know for that year what your rent will be, and you can estimate a percentage for repairs, but overall, you have a good handle on the income you will generate from that LTR for the year.
