On a 90 day rental even 1/2 month takes a huge percentage of gross income, so basically you need to eliminate use of brokers, MLS, etc.  

A HELOC and a Home Equity Loan are the same thing.I have an excellent residential mortgage broker who can help you with this, he's based in Orange County. 

For example, RentRedi gave us some trouble in refunding a tenant's security deposit and the customer service representatives also notified me that there is currently not a way to refund a tenant's security deposit after 6 months once the deposit is made which concerned us with long term tenants. 

Relying on a home warranty = bad customer service to your guests.  

I reverse engineered some of the Broadband Broker algorithms and could back-test against their whole sample set since I had all the HUD held-for-sale data on my PC.

Pre 2023 clients were overextended, stressed, and did not want to invest back into the house as they were busy living off the cashflow.Also as a broker, the same is true for my current buyers. 

Mostly that means a limit in the number of units you own, whether or not you broker it yourself or through an agent.

Terrible software, terrible customer service, and terrible company.

Decide the type of properties you want to invest in, find a broker specializing in those properties, decide on your investment parameters, and then start looking at for sale properties.  

Hire an experienced real estate broker to help you price and sell the property.
