We do the leasing for them, but once we get the tenant in place, turn it back over to the owner to manage. 

That's $400 cash flow per month, which is pretty good.Your first tenant moves in.

My tenant had an issue with the 1-year old dryer working.

@Paul Zofsak are the neighbors tenants too?

Lots of people who have trailers don't own the property they are on and sell them.As for the owner of the land expecting tenants to do repairs-there shouldn't be many repairs required to the land, just the trailer that is on it (which your grandmother owns and should be responsible for maintaining). 

HELOC are also highly reliable source since the interest rates are low.My tenants pay back the HELOC and TSP and now I have another cash flowing property.I think what you are thinking about is a great strategy

@Sean Anthony to us, this situation is really no different than a nonpaying tenant.We try to work with tenants, as "life happens", while keeping pressure on them by moving forward with the eviction process.

@Carlos Ptriawan there are several challenges with owning MHPs in a DST, as would be the case with most multi-tenant real estate. 

The first year was challenging meaning had a tenant but not saving, it was just making my living expenses cheaper.

@Derick JenningsRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?
