I have a network of aging friends and family with aging friends and families; it’s a whole new world of challenges; people don’t listen; they may be unrealistic beyond comprehension; they fail to heed warnings or do anything; and so on. 

Personally, I don't invest in anyone that hasn't lived professionally through the GFC, so by default I don't invest with anyone under the age of 45 yrs old.4.

BUT, i have a very strict criteria for leasing (credit score, income, no prior evictions, employment verification, no criminal record).

The most important question to ask  yourself is are these home ages typical in the area.

A healthy 401k and IRA savings for their age (early 50s), a paid for little old commercial building valued at 200k that is currently being renovated for wife to start a small business out of.

Build ages; you’ll find a lot of early 1900s homes here (Colonials, Duplexes, etc.).

I wish I had started at your age! 

Financing under 4 units is similar to SFH, though you’ll want to factor in age, condition, and insurance costs.Both can be part of a solid strategy—the bigger question is whether you want to buy all-cash with $125K or use leverage.

No obvious structural issues from the listing, but the age suggests surprises are likely.Rehab Budget: • Low estimate = $50K (light updates) • More realistic = $75K (new kitchens/baths, flooring, paint, code updates) • High end = $100K+ if major systems need replacingRents (CMA comps): • 1BRs: ~$1,400–$1,750 each (https://prnt.sc/RMm854WPuPdk) • Stabilized Gross Rent: ~$4,200–$5,250/mo (~$50K–$63K/yr)Cap Rate: ~9% if rehab stays in the $50K–$75K range, falls closer to 7–8% if it pushes past $125KConstraints:FHA 203k requires me to live in one unit for 12 months, so only 2 units would generate rent in Year 1.With 2 units rented, cash flow looks negative (~–$600 to –$900/mo).With all 3 units rented after Year 1, cash flow flips positive (+$600–$800/mo) and grows with rent increases.My Question:For anyone who’s done a 203k or similar triplex rehab — does ~$75K sound realistic for getting this building into clean, rentable condition (floors, paint, kitchens, baths, basic systems)?

Age plays a huge factor when it comes to comps.
