Hi Ruby,Many investors use their HELOC to acquire properties, so this could be a viable option.

I am not very knowledgable on the different loan options.

No loan options but Iv been really interested in modular multifamily and would love to know which company you are using and any other details your willing to share.I would love a modular triplex or quadplex here in the Asheville area.

Hit me up, and I can discuss the best options depending on the goal. 

Option 1&2 are obviously easiest/quickest.

I feel bad when people get sucked into sub-par turn key deals when there are much better options for investing in real estate more passively like investing in syndications or being a financial partner on smaller scale deals with another investor who wants to put in the work but needs the capital (I partner with people like this). 

@Matt Roth for mailers there are various list providers that provide different filtering options, absentee owner, by county, state, type/size/class of building etc. 

.- buy a property with two unit zoning and build an ADU on the backLots of options.

If you wanted another option and do not need the quick cash you can always build the unit rent it for a year and then sell the property.
