Long term $ can range from 6's-10% range depending on all types of factors - LTV, location, unit count, debt coverage, borrower strength, full doc or lite doc programs, etc..

Ensure your projected cash flow covers expenses, including higher insurance and management fees.If you have anymore questions, shoot me a DM or email!

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).

It is small multifamily with 30 year fixed rate debt. 

If you're willing and able, I do recommend the "house hacking" strategy which is just a fancy name for buying a rental property and living in one of the units, because you'll get very favorable financing - an owner-occupied fixed-rate 30-year mortgage.I'd also say, analyze that property as if you won't live there and it's a pure rental, and make sure the property is still cash flow positive if there's a tenant in your unit because then you'll know if it's actually a good investment.And when you analyze it, include payment of a property manager in your #s because if you don't, and doing so would make it go cash flow negative, then you've just bought yourself a job because you literally can't step away from managing it without losing money.

Alternatives include using a 1031 exchange to buy a new rental property or completing the exchange first and then doing a cash-out refinance to fund the ADU.

Forgot to mention, most accountant, myself included, have a secure portal to upload documents, many of the documents come in electronically anyway, so it really is very easy

An update one year later after this post, I now have:- Got my property and casualty license and wrote 370+ policies in a year- Saved up a few more thousand dollars in investable cash, paid off $20K in debt and raised my credit score by 100 points- Launched a direct to seller cold email marketing campaign and generated leads for cheap- Got connected with a few real estate investing communities like Subtle Asian Real Estate and Pace Morby's SubTo- Aggressively read and studied as much as I can get my hands onThat being said, I decided to run a marketing campaign to generate distressed seller leads in Phoenix, Arizona, mostly because:1.

The majority have evictions on their record, don't make enough income or have a lot of debt under their name.Comparing other rentals on Zillow, my asking rent is $1100 while other properties are trying to rent at $1200.

Also, how do I protect my assets if I use a solo k for a down payment but still need debt financing to purchase a property?
