3 apartments - probably a C+ to B- building in a C location:#1 2BR Rents for $600 currently#2 1BR Rents for $480#3 Efficiency rents for $500.Apartments 2 & 3 are on the same electrical, so their electric is included.

but a lot goes into analyzing a deal, including: $/SF, Average Days on Market in the area, how easy or difficult it is to get permits in the area, how long the flip would take, comps/ARV, Rehab, Rental Rates, how the area is trending, holding/carrying/hard money costs, closing/commission costs etc.If you can analyze the deal, you can then negotiate the deal with sellers, buyers, and lenders.

The smaller parks are generally owned by a now aging senior population who are not the least bit interested in emails or campaign letters.

Send me an email and I'll get you some contacts to get you started. 

Financing assumptions are a 30 year fixed rate mortgage with 4.25% APR and 20% down payment including rehab cost.

Few free to send me a PM or send me an email.

In the meantime, I'd suggest teaming up with an experienced investor (for a profit-kicker on your next few deals) to simply leverage their experience as part of your team for that deal and to include them in your underwriting package (your lender pitch).

Then lookup the owners contact information on the New Castle County Parcel Search and send them mail pieces (if you don't have the money for this than physically show up at their house and knock on their door), letting them know you're interested in purchasing the house. 

But if you marketed the property that "all appliances included", then that is a different situation. 

I know plenty of people these days that have no domicile (homeless), but use some address to get legal mail.
