Write-offs are great but it becomes the catch-22 for self employed people all the time...they write down their income but also their ability to borrow. I don't think you'd even want to consider a hard money loan...as you'll likely be creating a nice rental property for them when they take it back from you. As the others have said, HMLs are strictly for short term.....in and out deals which you aren't doing here.
What was your taxable income for last year? Most importantly, what is your credit score? You will need at least 3 lines of credit with no lates in the the past 12 months to qualify with most lenders. You may want to try and qualify for a lender handling the FHA 203 streamlined loan in your area. This loan will allow you to purchase a home needing repairs/upgrades where the funds for repairs are included in the loan. It's a 30-year loan and perfect for people like you who intend to live in the property. Homesteps is also a good program to take a look at as they have a similar program. You will still have to qualify for the loan though and that will be based on credit & income. You might look at Carrington Mortgage Services to see if they are active in your market with the 203. While not intended to be used as an investor loan...you can use the loan every two years. A common strategy would be to live in the new unit for 2-years...rent it out preferably as shared housing with 12-month leases and then qualify for another 203 for the next unit. Over the years, I have worked with several clients who have used this process to get mortgage free or build up a rental portfolio. Happy Investing!
