Plan to buy at 4 duplex and a single family(which includes a lot) this year.

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

This means building a budget that includes setting aside funds for your next investment.

Penalties of these Federal charges may include:30 years in prisonUp to $1 million in finesThey have a "statute of limitations" - (with a third "T"  ;-) of 10 years from the date of the transaction - 10 years from now, you could get a very nasty call and hopefully, you put your reserve money in a good account that grew to cover legal expenses**********************************************And the universe could blow up as Doc says in Back to the Future " But, granted, that's the worse case scenario." 

Common fees will include a set-up fee, a leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more.

How many units are you including in the $67,200? 

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

Now we are mostly scaling our business with larger communities but I've used many different creative finance strategies including seller finance, private lending, hard-money, collateral from other properties, and lease-options. 

I live in Charlotte and would prefer a multi-family investment property that is within a 3-4 hour drive so I'm considering areas that include: Charlotte, Raleigh / Research Triangle, Charleston, and Atlanta.
