This is a very popular incentive in the city of columbus where tax abatements can lower taxes by 3k a year. on income of 60k for a traditional triplex that we build that would be lowering operating expenses by 10% if you assume approx 40%. it makes a big difference but I was wondering if anyone has actually seen the benenfits over time from holding these properties or investing in similar areas in urban core adjacent through renovations or new construction. there are benefits to selling them obviously but please comment if this applies to you!! 

Xeriscaping (low-water landscaping) is increasingly mandated in many HOAs, and buyers are scrutinizing water-hungry features like traditional lawns.Rising Construction CostsMaterial costs have fluctuated significantly, and labor remains tight in the Phoenix construction market.

For example a "sofa" and "TV" and "desk", etc.

Yes but you will need to look for a local commercial bank to facilitate a HELOC or try a commercial lender for a traditional cash out loan.

She'll pay me market rate rent, thus keeping that money in the family, and the condo will eventually transition into a more traditional rental property that will support my retirement and that my children will one day inherit. 

Do most sellers prefer shorter terms (5-10 years), or can you actually structure something close to a 30-year term like a traditional mortgage?

I have spoken to lenders about traditional financing and also DSCR loans.

With seller financing, the seller acts as the lender, letting you avoid traditional bank financing.

Quote from @Alex Olson: Kansas City is a great market for Build to Rent and traditional garden style apartment complexes.  

Plus I pay a referral fee too realtors that can be close to the commission of what you were going to make selling it traditionally.
