If the appraiser believes the income approach is necessary for credible assignment results, then the income approach must be included.

I dont have the full purchase price of this 4plex to invest though, so I would have to finance half to 2/3 which seems like a stumbling block. i can still make the numbers work, but at a much lesser monthly profit i suppose. i also dont have the w2 income to support 2 mortgages (counting the one i have on my house), so i assume any bank would have to count the existing leases towards my income which i understand is possibleI guess I was wondering about advice, or red flags, anything, on this specific deal.

Also is the $41,255 NOI or is that just income?

I currently lead a family group of real estate entrepreneurs/novice investors who are looking to supplement our current incomes, build wealth and create financial independence for ourselves and future generations. 

Anyway, you are allowed to pay yourself,  but that turns passive rental income into actively earned income, subject to self-employment taxes @Nicholas Radina

The tenants are on a fixed income and were getting help from the other five family members for the 3,100 rent.

I would like to add to that I've just been busy with other stuff.I keep track of income / expenses for my 3 income producing properties in a spreadsheet.I also just bought a new home last year and still trying to sell the old home.

These are generally 12-24 month interest only loans that borrowers will generally pay back by selling or flipping to long term financing like DSCR loans.More on DSCR loans:DSCR loans won't use your income to underwrite the loan.DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.Here's a bit more in detail about how rates are calculated for DSCR loans:1.

Okay, then there's a lot you'll want to think about depending on your other income and your financial situation. 

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with zero or negative relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560, little to no good tradelines, lots of collections & chargeoffs, recent evictions.
