@Account Closed you can absolutely find $30k-40k properties in Indianapolis (I have purchased many) and, if rehabbed right, you'll end up with a decent cash flowing asset. However, there are some pitfalls with properties in that price range. $40k is going to get you a 2/1 or maybe if you are lucky a 3/1 SFR in a C or D class neighborhood that will most likely be at least 60 years old (likely older) and in need of quite a bit of work. You'll be replacing windows, gutting bathrooms, adding HVAC, repairing roofs, replacing doors, paint, floors, etc. You can easily sink another $20-40k into your purchase to get it rent ready.
If you do it right you'll have an asset with that will rent for $650 - $800. However, tenants in this rent range aren't always those with the most stable jobs so you may experience vacancies (or evictions) more often than is sustainable. Every time you turn your property over, you will be laying out additional cash for cleaning up the property, painting, yard work and repairs which could easily eat up a few month's rent and evictions add to that cost. Not to mention the lost rent when you are vacant.
As for BRR, while your house may fetch $80-100k if you do a higher end rehab in a good market, appraisals typically come in for far less and perhaps closer to your purchase price. So you may end up dropping $60-$80k into a property after rehab and only being able to borrow $30-40k back. That's not a bad thing necessarily but, unless you have lots of cash to keep buying, you will eventually tap out.
I am sharing personal experience here and not trying to discourage you. This model is working for me and the examples I sited above are worst case. If you work hard, you may find that diamond in the rough that needs minimal repair, cash flows great, attracts the perfect long term tenant and appraises well. Just don't count on that being the case. Best of luck to you!
