We had tried over weeks that we were working upstairs to pour all kinds of chemicals on them to eliminate the smells. 

If you have a vehicle that can tow, get a travel trailer.

The most important thing is to have your mailing address, vehicle registrations, credit card billing address etc changed to that property.

How do you allocate towards two different investment vehicles?

I'm contemplating rolling several very large SFR property gain amounts (via 1031) into a handful of DST Vehicles.

While the investment options of many conventional retirement plans are not amazing, as savings vehicles they have several advantages that will pay off in the long term.If you are in a 30% tax bracket, then when you make a tax-deferred contribution to your plan, you can put $10K in as compared to putting $7K in your personal control after paying taxes on income. 

I use 4 main categories of asset/liability:Retirement accounts/529 planLiquid equities (stocks/mutual funds)Real Estate (properties and bank accounts)Personal (personal accounts, vehicles)I was going to use personal capital, but they had trouble accessing all of my various accounts and I got uncomfortable with having a 3rd party have my usernames and passwords.

I applaud your desire to explore U.S. real estate as a vehicle for financial success.

If you wish to increase your investments as quickly as possible, If you are not adverse to risk, if you want to earn maximum return on your cash, if you want your property to generate returns as opposed to your cash generating the return, if you have other vehicles that will generate cash flow greater than the prevailing mortgage interest rates then you do not want to park your money in real estate and will see the value of a 30 year loan that is paid by your tennats.

@Mijin KimRetirement accounts are great vehicles for accumulating wealth tax deferred.
