First let me congratulate you on your phenomenal recovery
@Speedling. Although I'm sure you still have work to do there it's great to see you getting back to the task of family life.
I can throw out a couple of ideas that may be a consideration. Without having read this entire thread, I'll apologize now if I've reposted anybody's idea.
1) Anyway you decide to finance this, cash or 50% down, it should come close to paying for itself initially. That's before you factor in depreciation. Rember there IS a cost for using your own money. Depending on where you take it from, it may only be a only a quarter of a percent if taken from a savings account or it could be 5 - 8% if taken from an investment portfolio. The interest from any amount you borrow for investment property is fully deductible. So, if you pay a 5% rate for "non owner occupied" and your effective tax rate is 22% you are actually only paying 3.9%.
2) A garage addition can, at first glance, be written off over time unless used exclusively for you. So if the space is shared with a renter you have a foothold for a write off. My accountant, being anal but correct, would break it down to a percentage used by each but many accountants would give the wholè garage as a write off. Check with your accountant.
3) My criteria on buying rental property was to buy within a 25 mile radius of my home. That limits the need to hire out many issues reducing my income. This may be a factor depending on your skill level and availability for doing repairs.
4) As I mentioned, 3 years ago, on this thread I owned rental properties for 22 years with a very successful track record by following my personal criteria. 1) I would not rent a place I wouldn't live in with my family as that tends to attract people who won't care for your property. 2) As much as you might want/need that rent check I would leave a unit vacant until I found someone I liked. Once it took me 7 months. If I got their address early on in the application process I would do a drive by to check it out. Look at the car they drove up in. If it's a wreck your house may look the same when they're done with it. 3) Do your homework. Let them know you'll be running a standard financial & corey background check as part of the application process. Ask them if there is anything you should know before this is done. Have them front you the fees for these checks. If they have skin in the game they are unlikely to lie. If they walk they are hiding something. If you use a broker look over the paperwork DON'T take their word for it.
My 22 years in the rental business were, comparitively pleasant. I had only 3 legal issues as opposed to my friend who has legal issues monthly. Two of my issues were caused by sellers unwilling to loose a months rent, during the selling process, who rented to unscreened tenants that they dumped on me. Only 1 was a tenant that I put in. I was able to get full restitution from her without a court appearance. You will most likely be dealing with family's though. Hope this helps
@Speedling. Good luck with the process. For the rest of you reading this I hope it helped put you to sleep.
