Funding for second home and renting out current home
I am a newbie to investing.I have a primary home and converted part of the detached garage into adu. I am currently getting 1700.00 per month for rent. I have been renting it for about 8 months now. I would like to buy another home and then move in. I want to then rent the main home as well. Will the lender consider the rental income to reduce my DTI? I The combined rent I will receive from both will pay for my mortgage and give me cash flow of around $1500 a month. What is the best type of mortgage to use and can you suggest any good lenders used in the past? Since I will be moving into the second home can my down payment be less than 20%? I plan on trying to add or convert space into another adu and rent it out or fix it up and sell after some time.
Thank you in advance
