Option 1, pay for coaching to get properly trained on finding off market deals subject to and seller financing.

Not so much that you are better off it's that TTax simply can't figure it out unless you split the property into 100% rental versus partial rental in order to properly account for the personal use time.

If you are looking in DC proper, condos are great.

Zillow shows the property was sold - even if it wasn't (this happens more often that you'd think)I would ignore off market sales as your ARV since they won't properly reflect market value.

This furnace in the living room sounds a lot like my kitchen water heaters and should definitely be dealt with and properly this time if you plan on owning it for a while.

@Michael FriasI have actually done this not in Detroit specifically, but 35+ wholesales without ever seeing the property, it was while working for a real estate investing company, under an experienced investor who had more than 10 years experience investing, 10-15 VA's that I managed, and a bunch of systems that made this possible... even still it's not the best way to do wholesaling at all, and it wasn't my desired route but it worked at the time.The specifics as to why it won't work:You need to be experienced to wholesale properly.

This will require you to learn all the ins-and-outs of parks, to include filling up spaces, renovating homes, selling homes (along with licensing requirements), carrying paper, crafting the correct leases and notices, establishing the right park rules, proper tenant communication, metering of utilities, and the list goes on...

Look at it from both sides since there could be even more risk with a tenant staying if they haven't been properly vetted for example.

If the current tenants are under a lease, you need to wait until the lease is up for renewal to increase the rent (and make sure you give them proper notice). 

I have a number of properties down-valley of Palm Springs proper, and did some research in Big Bear a couple of years ago.
