That said, I will still try to provide some “clarity”.Purchasing a property “subject to “ the existing debt can be done two ways.  

In the future, I'd request a "soft pull" from a lender and provide them with your estimated credit score to get a rate quote.

We're based in Tampa and, in addition to personally investing, I own a mortgage company that provides financing for tons of investors.

Not here to provide an  endorsement or be critical of the lenders on this list but volume is not by any means an indicator I would rely upon when selecting my banking relationships.

If they did not provide a forwarding address we send it to the unit address, hoping they filed a change of address form.

Happy to provide more details.

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
