I'm particularly passionate about emerging markets in the Multifamily domain.Outside of real estate, I enjoy time with family and friends.

But for many people, it is one of a number of sources of deal flow, to add to MLS listings, wholesalers, direct owner outreach, auction, etc.Assuming you are specifically talking about sheriff auctions, just make sure you familiarize yourself with the general procedures for the auction.  

Get some policies and procedures in place.

I might try the “emergency service” which is $20 with limited data and just use that for the smart locks and ring cameras.

If you planned on moving out of a house and buy another property, as an example, you could pull a HELOC before you moved out and keep it as an emergency fund.  

I saved up the down payment for a few months and have a few remaining as emergency funds.

Screen tenants thoroughly, have a solid lease, and maintain an emergency fund for unexpected expenses.

Get on a budget, build your emergency fund, pay off all debts, save up.

For our larger park we have a 'Maintenance Manager' set up for up to 24 hours per week as needed with OT for after hours emergencies. 

While you might find a lender offering low down payment options, you'll still need cash reserves for repairs, maintenance, emergency fund (ideally 3-6 months of expenses), etc.
