I looked into a program that is called the rei accelerator and they said they will guarantee me a deal of a 60+ unit apartment building in the next 4 months and i will get to a closing table and generate $20,000 a month off my first deal with working with them.

I've also leveraged their webhooks to automate additional things on my end like setting the thermostat to the appropriate temperature an hour before the guest check-in and turning it off after they check out.

Recognize buying rent ready units have very thin margins and most properties purchased off the mls will have negative cash flow.  

I was wondering is starting off with an 2-1 apartment for around 75000$ in Gainesville Fl is something I should look into 

Someone with $10M in the bank in cash just needs to put a lot of money to work and time value and tax write off is more interesting to them than a hungry investor in their 20s that has never found a deal.Honestly, books are great, but they are about as "boiler plate" as you can get as I'm sure you're discovering.

Work in a balance reduction if you pay it off early?

Quote from @Jeff Roth: Hi Lina from Texas-Congratulations on your interest in investing in mid-term rentals and you are wondering how and where to get started.I get this question frequently from investors.Sometimes and investor is looking to keep their property cashflow positive as insurance and taxes have squeezed cashflow by turning units into mid-term or short-term rentals.First off, ideally, the property will cashflow as a long-term rental should something disrupt the mid-term rental model.You will also want to have the property be near where there would be a demand for mid-term rentals (hospitals, universities, research centers).Monthly rents for mid-term rentals are about 20% (+/-) higher than unfurnished similar long-term rentals.There are property managers that will manage mid-term rentals for you and I always advise my clients to use property managers to keep their investment as passive as possible and for compliance issues related to Fair Housing Laws and local regulations.To Your Success! 

I fell off the wagon when I saw a bullet point that indicated all second story apartments have an elevator and their suggestion that it was possible to get 1000% Plus Potential Cash-on-Cash return in the 1st Year.Where has SCDC built?

Quote from @JooYung Choi: You could consider going for a STR in a vacation market that will give you way more cash flow to pay off the HELOC quicker.

You may be better off trying to connect with some agents or other investors/wholesalers in your area and try and get off-market leads sent to you.
