Hi Clayton - a few thoughts here:
1) Conventional loans will add back depreciation when looking at rental income. These include insurance, mortgage interest, real estate tax, depreciation, amortization, and any HOA dues and can be added back to the NET of what you reported on tax returns. If you are looking positive after this, I'd recommend having a local lender run numbers for you as you may be able to qualify
2) While the $90k from your wife may not qualify alone with what you are looking for, paired with the rental income, it may push you where you want to go.
3) Future rental income of the subject property can be considered for conventional financing if you chose to purchase it as an investment instead. Ideally, this would mostly offset the future PITIA of the property you are looking to purchase.
4) Unfortunately without a 24 month history of 1099 income, you cannot use this toward qualification.
5) See if another family member would be willing to cosign with you (as mentioned above)
Best of luck!
