Lower Manhattan has seen great Commercial to Residential conversion as a result.

Scenario A (typical) - $500k duplex-$125k down-$375k mortgage at 4.6%Scenario B (modular financing) - $500k duplex-$125k down-$260k mortgage at 4.6%-$75k HELOC on primary residence-$40k loan against 401(k) (technically this would be $165k down, but you get the point)In scenario A, paying off the mortgage quickly makes zero improvement on cashflow until you pay it off completely, or refinance, and there's no point in that if your rate is locked in lower than current(or future) market rates.Scenario B could involve higher interest rates on the HELOC and the 401k loan, but you have multiple, simple, easy options for increasing your cashflow, and then you don't end up playing as much in the overpriced, volatile stock market.

Peter would depend what your current liquidity and net worth is along with your annual income from your job/business/current investments etc.Different assets are cycling at different points in time in different states.2009 was mainly coming off the bottom for the lower priced SFR assets. 

Is it lower income?

I have not, over my career, seen modular able to come in lower cost than site built, assuming you have good subs on a site built property.

I do not want to start out with lower rent, I fear them moving our in a year when there lease is up and having a half finished basement. 

Your Vacancy Reserves Amount is lower than I like to maintain.  

Even with lower rates, we are making a good return, but wonder where this will all go in years ahead with oversaturation and regulations.

I seem to have 1-2 people a week now reaching out to ask for PM advice in Milwaukee and thinking we need an additional market due to 1) pricing and 2) diversification.Fort Wayne IN still works for us but is getting pricy and with lower rents maintenance and eat into profits - Would like to start converting this properties to seller financed deals over the next few years.

These people didn’t want to buy, even though the payment with taxes and insurance was about $200 lower.
