So, your focus may need to pivot from high rental cash flow to little to no cash flow as a rental with an appreciation upside.I would recommend taking your $150K to $200K and securing a solid equity position in something that will cover its expenses and maybe provide a small cash flow, but then is poised to appreciate nicely over the course of the next several years. 

@Sung Yu You can 1031 exchange your fourplex into a single-family home, provided it’s initially used as an investment property (rented for 1–2 years) to meet IRS requirements.

Hi Nida,I'm a bit late to the party but better late than never I guess lolIn the search bar here on Bigger Pockets or even a Google research will reveal a lot of info about certain companies.I'd always like to joke around and say that "Google is your best friend" when looking to work with someone new lolI'd like to second Jason's comment who has been around the turnkey game for a long time and has probably conducted due diligence on many if not all turnkey providers over the years.Not many have stood the test of time and I'm proud to say that we have.Not intending to plug my company as we have many battle scars that started from day 1.But still here and still battling away 🤓Why we survived and thrived unlike many others was keeping our operation small and boutique and only doing deals on our terms.Low volume sales and thorough investor pre-qualification (As not everyone that has a pulse is necessarily a good fit for what we can provide).Some investors did better than others but one thing I can happily say is that we always did our best for all.I believe a very important component to any "true" turnkey company is that the penny ultimately drops must drop with them.Meaning, if you invest and things don't go the way as planned it is entirely up to them to rectify.No finger pointing or passing on the monkey to someone else (Like a realtor, contractor or PM).A true turnkey company stands behind it's properties, rehabs and in-house property management.Key phrase here is "in-house property management".Everything must be under the same roof and the provider must take all responsibility for the outcome of that investment.Wishing you much success

@Vina Merrill,I don't have much intel on Knoxville, but I’m active as an investor, turnkey provider, and builder in Chattanooga.

If I invested 100K today, they are currently providing anywhere from 60 to 72% passive tax deductions due to cost segregation, depreciation, etc. 

Quote from @Malcolm Brown: My real estate agent provides listings (multi family homes).

Yes. we finally have an APP that lets us provide a rating for the renters.

They provide fake checklists saying units are repaired according to agreed-upon inspection reports only to walk in to a home that is more damaged than it was during escrow.

We don't tend to get them when buying from a bank (because they usually won't budge on price) or wholesaler (who often provide an inspection) but do our own thorough inspection. 

You should check with your 1031 provider quickly.
