Although I don’t have experience in house flipping yet, I’ve successfully run a construction business back home.Due to the war, my family and I had to search for a new place to live.

These are you law abiding, working, fair % families probably plenty with US born kids. 

Quote from @Shannon Vistisen: Good Morning,I'm working with an investor (family) who owns raw land within an LLC.

With good software available so readily I'd say nah, but you have a partnership with non-family.  

However, there are still plenty of tax benefits when it comes the income you generate from your multi-family property that you can deduct from. 

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. 

Rents are high in this town and I think folks just don't sell their multi-family units very often.  

Investment Info:Single-family residence buy & hold investment.

Are you marketing to families/groups or couples?

Each agency has slightly different criteria and limits but the process for setting rents is roughly the same and has 2 components. 1) The tenant voucher is based on the tenant’s specific finances and number of people within the family unit.
