Going for second trip in January for some more research. 

The buyer ended up buying and reconverting to a single family, and doubled his purchase price.Yeah, that's actually a really good and in-the-now viable strategy. 

He negotiated a $5k discount on the purchase price, and I moved forward with the deal.Fast forward to now - after seeing water in the basement, I hired a professional to inspect it, and the news was not great.

Also, important to confirm they will be warrantable condos for end buyers otherwise it will be very difficult for end buyers to secure financing and thus purchase the units. 

I have purchased my first home already!

I want to purchase my second property within 4-6 months of moving into my multifamily house hack, but looking for a guidance on the strategy to do so.

The rule of thumb for me used to be that the property needs to be able to do 20% of the purchase price in gross rental income.

I can help with the refinance to pull equity out, but no the purchase, as 99% of the industry won't finance mobile homes. 

Quote from @Michael Overall: Good day, If an investor has 10 rentals and wanted to over time sell them and put the money tax free from a 1031 toward a large purchase is there a process to do that? 

Many Realtors will suggest purchasing a property using a FHA Loan, to reduce your out of pocket money.
