I also found 1031 to MF is extremely difficult and time-sensitive.I've calculated with ADU addition as well, if the property is added with ADU, the gross income is double; but if one do 1031 to multiple smaller home OOS, the gross income is tripled.For MF, rather than 1031, I prefer just to do MF syndication with debt or equity offering.

Another angle is to recognize that real estate does follow a cycle and perhaps you might direct your free cashflow to paying down debt or building up reserves rather than chasing prices.

For example, I think we are late cycle, so I lean toward the safest part of capital stack which is debt (or debt free equity).

If so, great, otherwise you can just as easily 1031 in to a nice property near you (probably bringing in less rent but still no debt.) or you could use it for 1/2 down on two properties that would probably rent for more combined and have a low/manageable payment. 

Other than paying off the debt or increasing your income it wont improve your chances.Also even though your rental income is more than your current mortgage payments, that really depends if youre renting out a multifamily property.

I think it may be better to use that money to knock out my student loan debt or invest it on my own.

(The reason I would like to build is that in the market I've been looking a 90's 6bed 3bath 2 car duplex is selling for 280-290$)Keeping the remained to either pay off debt or go to auction to look for the next fixer upper. 

I was wondering if I should use the 10,000 dollars to partially pay for college with less debt or use the 10,000 dollars for an FHA loan for a house hack.

Do I wait it out and get a degree to make a higher salary and have debt?

If they are not sold, then when all assets have been liquidated the trustee will abandon any remaining property to the debtor (the taxpayer) as having not enough value for the trustee to pursue.
