I currently own 10 SFR and plan on adding to that, but I do like multi's for their scale. 

I know some people may not have the time to be a mentor so I’m asking if someone needs some extra help with their business.

But, for no extra outlay for the duration of the loan, you'll eventually own it outright! 

It needs lots of work on the house and I’m sure some areas are not permitted, for instance they added a bathroom to the garage.

My question was how people "deduct"/don't pay tax on those expenses.To provide numbers, again this on a property, but not one I currently own (tenant in place for 1 year so no ads, turnkey so should have low repairs, but I still use 8%).income 1250$/monthTaxes 177$/monthInsurance 100 $/monthmgmt fees 100$/monthmaint 100$/monthVacancy (not actual money put aside) 125 $/monthCapex 183$/monthmortgage 440$/month of which Interest 4000K/year (330$/month)monthly expenses:1225$/monthprojected net income: 25$/month

So say you start with a small MFH and then keep adding more doors in the same geo area, then the same property management can manage more doors for you.

As you get up to #7-10 mortgages there are a few extra guideline requirements, like more reserves required. 

Are mezzanines included in the floor space or added to it?

I don't think I'll cash flow here, so I ran my numbers only on the money I needed to pull out to have no cash in.Financed amount is $100,000The monthly mortgage payment came out to be $435.59 per monthAt a 5.125% rate on a 30 year loan, I calculated a Net Renal Income came out to be $1,140 per monthI split the difference of the range and used $1,200 for an estimated monthly rent and added in a 5% vacancy rate.Expenditures came out to be $613.73 per monthI used an 11% property management fee, which was $125.40.I used $120 for capital expenditure reservesI used $60 per month for maintenance reservesProperty taxes were $225 per monthInsurance was $83.33 per monthThis put me at a Net Operating Income of $526.27 ($1,140 rent - $613.73 expenditures). 

If/when I do another flip, I'll get in with this guy, or a guy like him, and just partner and ride along, adding value however I can.
