I'd suggest focusing on your goal to purchase another multi-family, or single-family home where you can charge travel nurses per room/bed monthly rent.

Keep in mind these are duplexes so double kitchens, appliances, hvacs ect.... greater cost than a single family.

However, some lenders may have guidelines on how soon you can move in, so it’s worth double-checking if they have any seasoning requirements before converting to owner-occupied status.Refinancing Options – If your goal is to eventually refinance into a conventional loan or an owner-occupied loan, be aware that most lenders require 12+ months of documented 1099 income for qualification.

Appreciation - real estate values double every 12 years.

Quote from @Devin James: Gross Margin is an important calculation for developers/builders.Gross Margin = Gross Profit / RevenueWe shoot for a 20% gross margin on our New Construction HomesReal #’s:Home Sales Price: $374KClosing Cost: $18,700Cost of Construction: $258KLand Cost: $30KGross Profit = $67K$67K/$374K = 17.9% Gross MarginCame slightly short of our goal of 20%Homes Values and Build Costs are constantly fluctuatingI wish we had a crystal ball build larger homes. average new build in our market is 2200 square feet, 4 beds, 3 baths, 2 car garage and sells for 515k. construction costs lower if design is good and find the median or average home sale price and push that up. my guess is you built too small. 347k is cheap. we target 429-479k price range in columbus ohio for single family homes and also only purchase close to urban core where premiums are 20% higher and we build smaller like 1500 sq ft where price per square foot goes up. 

Fix it.We eliminate as much landscaping as possible: we take out flower beds and most decorative features, ideally, lawn mowing is the only job tenants have to do, because we know that's all we can expect from most.

For a duplex, I would prefer to stick with 3 bed/2 bath/2 car garage, but quadplex, I would probably have to settle for a 2/1 or 2/2 set up with no garage.
