Quote from @Bryan Maddex:
Hello Joseph!
This is mostly correct. Fannie Mae will allow you to count Boarder Income if you are purchasing a new Primary home, have had renters living with you for at least 13 months, have proof of receiving rental income for at least 9 out of the last 12 months, if you qualify for Fannie Mae's HomeReady program (which is an income limited program, you do not have to be a 1st time homebuyer to qualify for this program). In that instance, you can only count up to 30% of your income as boarder income.
As far as purchasing a new home as investment, you are allowed to rent that house as Longer Term whole house, Rent By The Room (usually called SRO for Single Room Occupancy, CoLiving, or PadSplit model), Mid Term (30+ day rentals), or Short Term rentals. Fannie Mae will use 75% of the Projected Rental income based on a long term rent model when purchasing that home to help you qualify for this new mortgage. Until this property is on taxes for 12 months, Fannie will continue to use just 75% of the lease agreement to help you qualify for future purchases.
Purchasing a new home with seller financing does not change how Fannie Mae would qualify your income on the next application. 75% of your long term lease agreements (to a single family or to individual renters in your property). Some lenders may have an "overlay" or may not be comfortable with SRO rental income on a newly acquired property, but I have done transactions using SRO lease agreements.
Typically speaking, if you qualified to purchase your primary residence, and you have not increased your debts or had a decrease in income, you should qualify for an investment purchase assuming you have a 25% margin on projected rental income vs the mortgage payment. Sometimes you may need to put more than the minimum of 15% down, or buy your rate down to help get numbers to qualify depending on what your debt to income is.
As far as DSCR loans go, many lenders do not like to work with 1st time investors but many lenders have no problem with this! Working with a Broker who represents a wide variety of lenders will allow your Broker to find a lending partner that fits your situation. You can do as little as 15% down on a conventional or DSCR loan, but rates/fees will always be higher than when you put 20 or 25% down. Multifamily (2-4 units) properties often times require additional down payment (Fannie/Freddie require 25% down), but there are a few DSCR lenders that will allow 15% down on 2-4 unit properties as well. If your lender told you that you need 2 years of experience, you are certainly working with the wrong lender!
Last, for your 2nd question, DTI works the same as described above but wanted to clarify that true seller financing, the seller would typically NOT maintain title or name on the mortgage. True seller financing would be provided by a seller that owns the property outright.
When you purchase a property under a "contract for deed" (sometimes known as installment land contract, a land contract, or a land sales contract), that is when your name does not go on title. Be careful with these transactions and get advise from a knowledgeable real estate attorney who works with these to make sure all steps are taken to property protect yourself.
When you purchase a home "subject to" the existing financing, that is when a mortgage stays in the sellers name. You are going to take over the payments of their mortgage. It is best to establish a 3rd party servicing company to oversee these payments as you do not want to send this money directly to the seller as they may not actually make the payment and then you could see your house foreclosed on by the lender. Having a 3rd party servicing company handle these payments can be a way to help ensure payments are made directly to the mortgage company and provide proof to both you and the seller of the property.
You can combine "subject to" transactions along with "contracts for deed" transactions to have the title and mortgage remain in the sellers name.
If you are doing either subject to or contract for deed transactions, please make sure you have your own representation in those transactions to protect yourself!
Let me know if you have any other questions, or if you want to talk further about traditional or DSCR lending!
Thank you for the very detailed response! There were many gems in this! Also, thank you for clarifying more about seller financing and recommendation about having a loan officer find the DSCR vs. direct! I've heard of "subject to" but not "contract for deed." Mainly some horror stories surrounding what you mentioned (not sending payments to a 3rd party, and then the lender activating due-on-sale).
I'm definitely interested in DSCR since it I'm also a travel medical worker and have gaps in work history (will have another one in November), which could make traditional financing tricky (proof of employment).
